The Vegan movement was based on an ideology and that ideology is the mechanism that propels this forward. That, and then misinformation about the actual nutritional value. There's no hard evidence behind the benefits of a vegan diet, only the opposite.
So why does this market continue to expand like this if it may not even be healthy for you? and it sure doesn't fucking taste as good. Americans love to eat shit, but at least that shit tends to taste good and fuck with your pleasure receptors in your brain.
Veganism, and to some extent Vegetarianism doesn't do any of those. There's no pleasure, only hassle, and possibly health consequences on the same levels of eating garbage fast food. Yet, it continues to grow based on a false premise.
I find that interesting and disturbing. You autistys will just laugh
