I hated steak well into my 20s because I'd inadvertently always eaten it well done and thought that's just how it comes. Since discovering the rare end of the spectrum, I now love steak
I'm not going to try every variety of bean in the world just to find out there are a handful of beans other than some peas that I might possibly like. Just like I'm not going to try every variety of olive I like just to find out if there's one I don't hate.
Why does this even matter to you? You eat what you like and I'll eat what I like. Notice I haven't even asked you what you eat and if you told me you didn't like, for example, fish, I wouldn't keep pressing you because there are lots of types of fish and you just haven't tried the right fish and I thought I didn't like fish so you're mistaken for not liking fish. Would you enjoy it if I kept pressing you on it or do you think you might consider that rude?
Again, why does this matter to you? Why do you care so much about what a stranger chooses to do? Am I hurting anyone? Am I being highly immoral? What is the deal here?
I think you're hurting yourself by depriving yourself of an opportunity for delicious food.
Also it's an online conversation, you can disengage whenever you want. It's not like I'm a door-to-door evangelist trying to preach the glory of beans.
