I'll admit that I have a tendency to kill things that cause me serious problems. Rats, mice, certain insects, excess possums & racoons, etc. I've been known to leave things alone that I could kill but aren't a threat to me...like coyotes, foxes, skunks, crows and snakes. I've never experienced the gut-level fear and loathing which causes some grown men to kill snakes as fast as they find them, and because they can.
I'm in favor of the incidental harvesting of snakes for their skins, and I love a good skin-backed bow. I'm really not in favor of the "kill 'em all" philosophy though, as they are another valuable creature in our ecosystem.
Trespassers like the python...NOT included!
