“I never said anything about what to eat.”
Yeah. You never said anything about which interpretation of quantum theory I should hold either. I'm free to decide what to eat and still be a Buddhist.
“You are ego tripping.”
I'm always ego tripping until I become one of you. Might as well not eat animals while I'm ego-tripping.
“You kill sentient beings indiscriminately anyway. And what about the bacteria you breathe?”
Yes. But I'd rather be a hypocrite than a cynic. You are using the same logic people have always used against vegetarians. I read a seventeenth-century pamphlet against Thomas Tryon that said the same thing: look, he wears shoes! Shoes, people! Leather!
I'd rather be a hypocrite who doesn't eat animals than a hypocrite who does, or a cynic who does and justifies it by using you as a stick to beat me with.
“You are just plain wrong. You'll suffer in your next life! You disrespect me!”
Now don't go getting all theistic on me. Luckily as a Dzogchen practitioner, I abide by this: even if the Buddhas of the three times rise against me, I know I'm not wrong.
