Why do Vegans.......?

[stevo]

I'm not vegan but to say "it's not natural" is very odd. What exactly is natural about the way we slaughter animals on an industrial scale for food?

Consuming the breast milk of other mammals isn't very natural either

Not all vegans choose to eat meat-like alternatives. I think partly the reason why such foods exist is to try and demonstrate and appeal to carnivores that there is an alternative.
