> Also some people back then would brag about not having a TV, the same way vegans still do today.
This is the toupée fallacy mixed in with something else I haven’t yet put a name on.
Most vegans don’t brag about being vegan, just like most TVless people don’t brag about not having a TV. Some people are assholes and brag about anything, and some of those do the things you mentioned. It’s orders of magnitude more common to see people complaining about vegans (or, for an HN example, Apple users) than the actual bragging. It’s a meme, not the reality.
