Antonio, why do you bother arguing with some hippie who can't accept basic facts of life?
Humans are omnivorous. Humans have a position in the food chain. Not eating meat goes against those facts of life and we shouldn't leave a small brainless minority too weak to accept the laws of nature transform human alimentation in an unnatural way.
Are you actually arguing that anything that's evolutionarily useful is necessarily moral, and asserting that someone would have to be unintelligent to not accept that premise? That is your argument? Think about it for a good minute.
Such "moral" overthinking is what led to oppression of women during millenia and oppression of gays until a few decades.
Religions created plenty of bad moral codes. It's the same for vegetarianism. It's a misguided moral code, guided by an higher concern for animal life than human life, which isn't acceptable for a well-balanced human.
Are you really arguing animal health is more important than animal health?
