Okay, to start off I'm a rat/mouse owner. Also I have absolutely nothing against keeping snakes as pets(I'd actually rather like to have one myself, just don't know what kind to get, I'll get into that in a bit
) and I also don't know much about their care, so if I'm off base somewhere please correct me so if the info that I have posted is wrong somehow, I'd like for this to be as correct as possible if I end up being able to get enough support/information to mail it in. Also if I miss something, please do tell 
I know that the majority of the snake owners here whole heartedly are against the use of live feeder mammals(no matter what kind they are) and since I love my fuzzies I was looking into doing like some countries have done and seeing if I could mail letters(chains of them would probably be nice as well) to see if I/people who think like I do could get the US to pass a law banning the sale/trade and feeding of live vertibrate animals to animals(since snakes aren't the only ones who eat them) unless the snake is in danger of dying of starvation.
The big points I was thinking of using are as follows:
I know that a lot of snakes areinjured/killed each year by feeder animals that just didn't want to be eaten. I've heard some stories... There was one person at a vet's office I went to once that was saying that her boyfriend's snake had been nearly killed by the rat they had given it, yet they still were feeding it live animals. I know it is a big misconception that they can only eat live rodents(look at all the ones who do eat frozen/prekilled meals) There is another person I know who watched his friend's snake be completely devoured by a rat, and still insists that if he ever gets one(which he wants to do) that he will still feed it live rats(though I have the feeling his wife would not let him, she adores my rats). I briefly worked at a pet store in FL and the owner of the place did not do anything to debunk that myth. He'd tell people that the only thing that a snake should be fed is a live rat/mouse ect. depending on its size. I asked him about it one time and he claimed that since that is all they would have in the wild, that it was the only way to feed them. The best I've heard from someone is that she refuses to feed her snake living prey because she doesn't want to lose a $50 snake over a $5 rat.
The claim that "that is what they would do in the wild" is ridiculous in my opinion. I know some snakes eat birds/other reptiles/insects ect in the wild, so why are these pet store owners promoting rats as a staple diet vs. a varied diet resembling what the snake would eat in the wild, when it would be much healthier that way? I'd rather be feeding my pet a balanced diet that would make it healthier and longer lived than an unbalanced diet that would end up making it die of malnutrition a few years before it would have died of old age. Plus, you can't seriously expect for me to believe that a snake that lives most of its life in trees would make a special trip to the ground whenever it gets hungry just to snap up that tasty rat, when it has birds right in front of its nose. If I put my oscars into a goldfish tank they would eat them until they explode, yet goldfish have chemicals in their blood that prevents an oscar from absorbing the vitamins that they need. Plus they eat more veggies and insects than fish, thus ending up with a severely unbalanced diet if only fed those goldfish. Tasty? Yes. Fun to chase? Definately! Good for them? No.
More against that argument is that there ARE other animals out there that would eat live foods in the wild. If I let them, my rats would kill and eat my parakeet, and my mice. Does this mean I should give them a diet consisting of nothing but mice and parakeets? I should certainly hope not. They eat their cereal and pre mixed diet fine. And the only kind of meat they get to kill for themselves are crickets. Also on this subject, in the wild an animal has a chance to excape from its potential eater. In a tank that animal must stay with the snake until it decides that it is hungry. Sometimes the snake will eat it right away, other times it won't. Then that feeder must live in close quarters with something that is to eat it, without food, little water, and not too happy of a remainder of its life. Either to starve to death, or to be suffocated/poisoned and eaten.
I have read that feeding animals live food will increase their agression level. This may not be so bad if you never handle your snake(though what happens in the event of an emergency when you need to handle it to get it away from danger, or to a vet's office?) but for the people who do, I'm sure that it isn't a good thing that moving things normally equal food. Especially not for your hands.
Also wouldn't it be better to feed your animal a frozen rat that was fed a healthy diet and then killed, instead of one who lived on hamster food and is half dead while it is alive? Rat housing in most pet stores is notoriously bad. Aren't there certain illnesses that a snake can catch from a rat? Parasites at least, right? Especially if they are crawling with illness. The frozen ones on the other hand are sterile and cannot transfer disease. A question that comes to mind is that pine and cedar bedding are toxic to rodents. The oils from them can kill them, and they will accumulate in the liver of the animal as it is trying to rid its system of them. Would those toxins also be bad for snakes? I know I've heard that it is bad to house reptiles on them as well, yet most stores that sell feeder animals house them on the pine or cedar just for cost effectiveness. I also don't see why pet stores would not want to sell the frozen feeders for their own gain as well. When you have to keep animals alive you also must pay for supplies for them(at least the ones who are good enough to keep their animals fed and on some sort of bedding instead of in a bare tank with nothing to eat except their dead cagemates) With the frozen ones they would only need to pay for the animals, and power to a freezer, which most of them have anyway for fish food and worms. I'd think that would be better than keeping live animals on hand to care for, even though most of the time they don't get any sort of care. A lot of people on the rat forum I am on have told horror stories of finding rats with massive abcesses and infections, wouldn't that be bad for a snake to consume?
I'd also think that it would help end irresponsible breeding of rats and mice, since they would be looked at more as pets rather than only as snake food. And I'd think it would do a little bit to curb people just going out and finding a snake in the wild and bringing it home because it was pretty, wouldn't a wild caught snake be a lot less likely to take to frozen foods than one that was bred and sold as a pet?
That is about all I can think up off of my head. As I said, if someone can find something I missed, or add onto what I already have please do 
I was also wondering what kind of a snake may be good for a beginner? I would not be able to get one for quite some time most likely, but I want to gather information before I do happen across one and find out that I have no idea what I'm doing. I love garter snakes, unfortunately the pet stores around here will not stock them since they can be caught wild, which is something I would not consider doing. If I do end up getting a snake, I'd like to get one that will stay small. If anyone knows of a snake that doesn't ever get to be more than 3 feet and can be handled I'm all ears
Otherwise I would not consider something that can get over 5 feet normally, or that has a hard time adjusting to frozen foods. I'd also like one that I could handle. Oh well, as I said, just thinking of a maybe I'd like to someday
