I find it frustrating when somebody replies as if they've only read one sentence in a paragraph.
I also said, "I like animals and I eat meat." I thought that was pretty clear, but if you'd like me to beat the point to death, the cognitive dissonance is between my fondness for animals, cows included, who I would never personally hurt and don't want to see killed, and my fondness for a good cheeseburger.
Could I come up with some contrived rationalization which somehow includes both? Sure, I have in the past, and many meat-eaters do. But ultimately I saw through my own bullshit here. Cows aren't essentially different than horses or dogs, but I eat cow while I'd be horrified to eat horse or dog. This doesn't make any logical or moral sense; it's just what I grew up with and am used to. When I think about it, I experience cognitive dissonance. For some that dissonance resolves into becoming vegetarians; for others they just refuse to think about it, or become dickish anti-vegetarians. I'm only different in that I have worked to get more comfortable with that sort of dissonance, as it's important to me to see things as clearly as I can.
