Sorry, but anyone who tries to tell me I shouldn't eat meat, or use dairy is stupid, end of story.
I have canine teeth, as well as molars. I have access to large amounts of proteases, lactase, etc, etc, etc, to fully digest my meat, milk and vegetable diet.
People who don't have sufficient lactase - i.e oriental, black, etc - due to not having domesticated cows, and their genes for lactase shutting down in adolescence, fine, avoid milk, it will make you windy.
Other than that get of your insanely unfounded high horse and back off. Humans evolved to eat most things - and as we continue to evolve (albeit a lot slower), we will start to be able to eat even more things, including the damaged fats that are currently messing with us.
If you want to be vegan, fine, just don't pretend it's anything more than not wanting to hurt another living creature - which I'm fine with. The problem is it is very hard for vegans to get things like B12 - and despite their claims to being ubber healthy, the majority of vegans I have met look like death warmed up.
