Yaoi

I'm a bit confused on this topic, but is it okay to like yaoi?

I've seen some people say yes, and some no.

And some people that say that its unrealistic, and it mocks gay men.
But then again with yuri its unrealistic as well?.. I know its not the same situation. This is probably stupid, idk if this is stupid or not.

So if this is the case then is it okay?... I'm sorry I'm not trying to be rude in any way, idk if I worded this properly.

Is this offensive?.. Because I've read it many times, does that mean im fetishizing them?
If I did then I didn't mean it. I'm a bit scared to read it. I just want this clarified
