Because there’s like a difference between a beef burger and the platonic idea of a burger. Like if I say I want a burger, you’re not going to fault me for buying a chicken burger are you? Even though it doesn’t taste anything like a regular beef burger? Same deal with veggie burgers. Meanwhile if I order a burger that looks like beef with the expectation that it will taste like beef, I’m going to be upset when it doesn’t taste like a nice beef burger but instead a rather shitty one

Also there’s tons of veggie burgers out there, maybe you just gotta try some that aren’t like, the weird “healthy” options that dominate the search results. Stuff like a big ol’ falafel in a bun or deep fried aloo tika.

…also I don’t actually like beef burgers that much
