I don't have any guilt about my food. I butchered a deer once, that my dad shot. I know where it comes from. It fed Mister and me for a good two years.I tried the leaving out meat for health reasons. It didn't work for me.
I have been attacked by a vegetarian. Only one. I had to take it because she was my boss. But she wore leather so I don't know what that was all about.
My other veg friends don't tell me what to eat and I don't tell them what to eat. That's a really personal choice. Leave my food alone and I'll leave your food alone. I don't think that's too much to ask.
