the next time you see your jewish friend, say "hey you jew" and you let me know how that goes. it is demeaning specifically because it narrows down the person to their ethnicity/race/religious background.
it's the same thing as calling a muslim an "arab". sure, it's not derogatory on its own, but it's almost always implying the distinction between them being just a "person" or other identifying noun and them being one of 'those' ethnic groups
for example, pranay could just say legit list of gay players if he wanted to make the distinction without narrowing them down to just being that to him
