well it's fine if you choose it as ur life style, eventho u have to find some synthetic sources for essential fatty acids if they are not included in ur diet or vit B12... but the point is that much of vegans try to make it look unethical to be a meat eater, and go on in controversy about axioms such as weather human is omnivore or Herbivore! that makes it look so silly, you can be whatever you want but without trying to impose your way on others who also like their lifestyle
