Frankly, the only soy product I EVER use is soy sauce on asian food. Otherwise I think it's disgusting. As for drinking another specie's milk... what is wrong with that? We've been doing it for millenia... *shrug* And cheese is a direct product... and butter. Saying that is like saying, eating peanuts is nasty, but peanut butter doesn't count. Sheesh!
At any rate, most "healthy" alternatives eventually turn out to be not so good. Hippies are poor judges of nutritional value...
