So relatable. I eventually went vegan, but as a kid this was me. The only kind of meat I'd tolerate was chicken. When my parents make some kind of steak, I'd cut all the fatty parts off the meat and end up only eating a few tiny bits. Then they would get upset because I didn't eat enough of it.
I never could tolerate the chewy fat. Which makes it all the weirder when meat-eaters eat beef and go, "You don't know what you're missing." Yeah I do, I'm missing a texture I can't stand, and that's a win in my book.
Curious, how do you feel about mushrooms? I find the texture similarly revolting, but with a rubbery texture added in. Then the smell when they are cooking... it's like somebody's cooking up dirt.
