Ayup! I recall having seen a PBS special long ago covering that concern (interspersed with the primary historical topic), citing some tribes of the American land-masses that most likely wiped themselves out by practicing cannibalism -- due to the truly nasty diseases that can be contracted that way. But hey, if vegans and "animal rights" lunatics want to prove their point that all other animals' lives are equal to human's lives then that's what they'll have to do to prove it -- promote cannibalism for an omnivore species! It'll be the ONLY way they can do it. :-) (I now envision them all having the lobes of their brains(what's left of their brains that is) throttling themselves to death in trying to figure a way around that little legal, moral, and ethical problem/dilemma of theirs to try to prove they've been right. :-) LOL )
