Do you think that people GENERALLY date in their "league"?

There are many trolls on this site, but there's one that always keeps coming back and if I point out that he has become boring, he tells me that I'm fat, ugly, and a new one, "lesser woman". 😂
Anyway, I showed my best friend his post and his replies to me and at a moment she said "He still hasn't figured it out that people date in their own league".

P. S.: When I think of "league", I include personality/intelligence and looks too.
