Maybe I should've specified 'features people typically associate with Africans' like dark skin, wide noses, thick lips, etc. I'm well aware black people are not a monolith and that we don't all look the same. I'm well aware some have European features and can even pass as other races. But you're splitting hairs right now. When someone hears the term 'black people' in a colloquial sense most aren't thinking about the vast genetic diversity in Africa and South America. I'm talking about casual conversation where the mental image the term 'black people' invokes is one of dark skin, coily hair, etc. My point still stands. If someone is not attracted to that mental image, that does not make them racist by default. They must hold other prejudices about black people beyond not being attracted to us in order for them to be racist.

It's much easier to say 'I don't find black people attractive' when you know there is a general set of features black people have in common that you aren't attracted to rather than list them all just to avoid looking racist. People are lazy, and most of the time it's really not that deep. I'd much rather say 'I don't date people with kids' because that's easier than listing all possible caveats in which I might date someone with offspring.
