In a snake community, I can see it being a touchy subject. But the fact is, this is an invasive species posing a threat to the native ecosystem. While I may not personally be happy about so many snakes being killed, it is for the better in this circumstance.
I don't think they'll be able to wipe out all the invasive snakes in the Everglades, but population control (like they do with deer) wouldn't be a bad thing.
