I've had militant vegan neighbours when I was a student. I don't know how they did it, but they found ways of turning every conversation about them and their "superior" life choices.

Then there are the vegans I sometimes meet during my summer work ours; the ones standing on the street and bothering everyone walking past them in a very persistent manner. Like a jehova's witness.

I'm not saying every vegan is like this. I think I've met more vegans that didn't rub it in everyone's face than ones that did. But consider yourself lucky that you haven't met anyone like that in twenty years.

This would be the silliest version of it.

A burger or a sausage is more like a format of food rather than a specific ingredient of food. It would be like saying things sold as a "loaf" can only be made of wheat.
