Yep, you raise a good point...the "I've killed cockroaches, reptiles, frogs... ants, scorpions, bees," comment. People don't see it as killing though, but it is indeed killing. That's what ending something's life is...killing.
You say something... that you don't like to kill. And why do you do it?
I think I address this in the post itself.
I don't live in a fantasy world where people get to eat meat and use animal-based products but nothing actually dies. The reality of it is that animals die for human consumption and use, like I say, even in crop farming. So, I figure I need to cowboy-up and be prepared to do it myself rather than be a hypocrite. I've done a lot of killing, I'm good at it, but that doesn't mean I like it. I guess, the concept of my comment above (from my post) may be lost on someone who doesn't do it herself/himself. I am a responsible shooter/hunter and that means something to a hunter. (Or absolutely should! There's some who are irresponsible, but that's not everyone, that's the few.)
We all kill, as you so conveniently pointed out, and we all use animal products so I guess, myself included, so I feel compelled to take the responsibility for it.
