I have the same reaction, they are disgusting and sad. If we had puppy roundups where we slaughtered puppies, animal rights groups would freak, but because it is snakes (venomous ones at that) no one cares. Even Parks & Wildlife doesn't regulate the roundups - people participating do not have to obey non-game hunting bag limits and other regulations that are -supposed- to apply to the collection of all snakes in Texas. (I'm not positive about other states, but something tells me the are no better.)
There is a fine line between a hobby and a mental illness.
