What do you eat? Lentils? nm- you're too young for that one.
Anyway... do you eat beans? beets? carrots? soya? What do you think those are? Minerals? No, they're plants. Yeah, plants. Living beings, just like you and me and the cow I had for dinner.
So don't sit there all sanctimonious like you didn't kill HUNDREDS of wheat plants for the bun on your soya burger, and HUNDREDS of soya plants for the patty, not to mention tomatoes, lettuce, cucumbers, onions, and mustard seeds, and you have a cow over one single dead animal to make it a real burger?
And what did you have for breakfast? Oatmeal? Corn flakes? Wheaties?
I may be a murderer, but you're a cereal killer.
So unless you start eating quartz, STFU.
