In regards to why there are plenty of rather dumb snake bite incidents (like the latest kid from PA), it's because no matter how you cut it, venomous snakes are cool. Danger is cool. Extreme sports are cool, yet golf is not. It's because of the danger factor. It's the same reason every young male only seems to want either a pit bull or a rottie.
There will always be ignorant people, but the real blame goes to the lowlife reptile dealers who would rather make $40.00 selling some sickly WC venomous snake to a visibly naive keeper, than be a decent person for once in there lives and deny the sale and help protect the hobby they're glady raking in money from. But nope, it's a free for all, make as much money as you can while the gettings good. Only look out for yourself, typical home grown American logic.
If venomous keepers want to keep their precious hobby, I suggest not supporting unscrupulous and greedy dealers.
