..a common trait of asians...
There are facial features which are prevalent when it comes to black people...
they may find many black people unattractive...
That is the crux of the argument here. There's a difference between "common," "prevalent," and "any." When you take a perceived common trait, and generalize it to mean "any" one in a group in a negative way, that is called racism.
Eg I start a thread: "I like big butts... I don't find any white women attractive. Can someone show me one?"
I don't think any white people made good music. I think they just copied whatever black people started. Can someone show me a white person who started great music?
If I posted that, I would be trolling.
You don't have to have any doubts about that.
