Is it normal to not find black people sexually attractive?

... but it's no more racist than a guy who exclusively likes Asian women or a woman who prefers Latinos. Everyone has a type! Lots of people prefer blonds or brunettes, some people actually prefer Black people and some people even prefer Gingers. I don't think someone's preference or type is an inherently racist thing. Racism isn't so much a state of being as an action. A person may be or not be prejudiced, but it's that person's actions that are racist or not racist.

Regardless, people are entitled to their opinions and preferences therefore no one should ever owe anyone an explanation as to why they are not attracted to anyone!
