I think it's problematic to be too fluid with the definition of racism particularly when it comes to physical attraction.
Saying you don't generally find people with certain physical characteristics attractive, or as potential sex partners, doesn't include exceptions, or even mean a person is racist.
It's just a preference.
People only know their own experience. It's not fair to accuse someone of being racist in terms of sexual attraction simply because it's not what they're familiar with.
Every BM on this site doesn't think EVERY WW is attractive.
Not every WW here thinks ANY BM is good looking.
That's just how attraction works.
Who you fuck and vibe off of is a totally different decision process than who you will hire, live next to or admit to a university.
Anyway IMO it was more than this dude's race that this chick couldn't get with.
He seems like a poor match for her physically and a bit of a simp.
