First of all, I love eating meat, and I don't feel bad about it. I try to buy local as much as possible to ease my conscious. But eating meat for sustenance is different than killing a mouse cause he got in your house.
Second of all, poisonous spiders don't live in Northwest Ohio, but if I did see one I would smash the fuck out of it. But killing for self-protection is different than killing a mouse cause he got in your house.
Those are both weak analogies.
Thirdly, however you want to deal with your critter problem is totally up to you, and it doesn't really bother me at all, all I'm saying is that this is how I choose to deal with mine. I don't necessarily think there is a right or wrong way.
But lastly, and mostly, this isn't the politics thread, and this is the reason I ignore it.
