Well, I never claimed humans were "carnivores". I've always said, and most vegetrians agree, that humans are OMNIVORES. Meaning we can eat BOTH plants and animal foods.
Another thing, I don't say anything about they type of teeth, just the enamel. the enaml of a human tooth is too thin as compared to true herbivores. It cannot withstand a lifetime of plant fiber chewing. Thats' why most people need to cook or at least blanch their veggies.
Vegetarians always claim that we don't kill our own food that we have to ue tools. Well, that's what Homo Sapiens means.. The Tool Maker. Thats' what we are. Vegetarians don't munch veggies off the vine like true herbivores do you? You pick it, clean it, process.cook it then eat it. You don't eat the worms, manure, plant diesease etc that one can find in a veggie do you? Do they sell manure covered, worm infested cabbages in the supermarket? No, they all all cleaned, wshed, sorted for quality etc. they were "prettied" up. You do not pay attention to the possibility that the person who picked that food for you, washed it, packed is probably an abused child laborer, working 12-16 a day and living in conditions woprse than a factory /battery chicken. It doesn't say it on the label I suppose.
Last, i always point out the gall baldder. The gall bladder has no other funtion but to produce bile. Bile is only necesary to digest meat. Humans produce copious amount sof bile (so do top carnivorous predators) but herbivoresd produce very little to almost no bile and many of them don't even have gall bladders.
If you see somebody say humans are CARNIVORES you know you are talking to a fool. or at least somebody seriously misinformed.
