There is some amazing vegetarian food out there. Both Buddhist and Hindu cultures have been making amazing vegetarian food for literally thousands of years and they are really good at it.
Also, vegetables are just yummy!
Fake meat, no thanks. Incredible vegetarian and vegan food exists, stop trying to fake it. Same with gluten free foods, almond flour is an amazing ingredient but it is different than flour. It is funny that the keto community had amazing gluten free recipes years before the gluten free communities figured it out.
What should they call it, then? Oat beverage? Soy water? No, that's silly. They are, functionally, milks. That's an apt descriptor.
Ditto for other vegan alternatives.
It varies by country.
On the "Soy milk" wikipedia page, it is said that Germany and Italy use names like "soy drink" or "soy beverage".
