Hey there!
This is probably going to end up being a bit long but I'll try to keep it as short as I can.
I'm 46, have a 9yr old son & 13yr old daughter, and live in a very small community in southwestern NC (Murphy, NC). I have firsthand experience with your concerns so I can tell you, "Don't worry about it, it won't be a big deal."
Yes, there are many ignorant people in small communities with the mindset you described, and then some. Cities have some of the same people but the small town folklores are burned in memory.
Case in point: I grew up in a small central FL community, catching & keeping snakes since I was 6, and I have hillbilly roots. My wife is from this area we live in now, in the foothills of the Appalachian mountains.
My wife and I spent our first few yrs in central FL where she watched me catch many Eastern Diamondbacks. We had discussed me getting back into keeping them one day. A few years after we moved back to NC she came from the woods holding a snake by it's head saying, "I've got you something."
When I saw what it was I got mad at her for catching it and asked her, "What are you doing with that?"
"I thought you wanted one," she replied.
"I don't want a Copperhead," I told her.
She started to panic a bit, extending her hand/arm with the snake in it as far away from her as she could and started saying, "Oh my gosh! Oh my gosh!"
I asked her, "What did you think it was?"
"A rattlesnake," she said.
"Copperhead, rattlesnake, what's the difference?" I asked.
She threw it down and she told me about all the folklores she had heard about Copperheads. The difference in her belief was that even though I told her how dangerous rattlesnakes are she didn't hear false, freightening tales about 'em like she did Copperheads. She respected rattlesnakes but feared copperheads.
While a lot of people fear snakes I've found that very few are deathly afraid of 'em and curiosity overides typical fear in most cases. I've only had one person refuse to come in my house because of snakes and he's a friend of mine. To be perfectly honest, he ain't playin' with a full deck anyway. Ha! Ha!
There has been a time or two when I knew a kid's parent wasn't too fond of snakes and I tell them that the snakes are in secured cages and I won't get them out if they don't want me to have them out around their child. Let's face it, no parent in their right mind is gonna let their child go to someone's house without knowing them well enough to trust them.
Of course, sending pics to school with your child of them holding snakes does wonders. The quickest way to a parent's heart is thru their kids. Create the interest & education in another child and you stand a good chance of winning their parents. I've got parents that are afraid of snakes asking if they can bring their child over to see my collection.
So, from experience, it's a non-issue. Don't worry about it. 
Take care!
