Is it racist to think one's own cultural values are superior? The short answer: yes. All values must be judged by reason, and to accept one over another simply because it is of the culture that one has sprung from, is unreasonable prejudice. — Metaphysician Undercover
No, it's not racist. Even if it were "unreasonable prejudice", unreasonable prejudice is not racism. Racism is about races not values. It's the belief that race, which is biological in so far as it exists at all, has some effect in and of itself on determining morality or other desirable personality traits. It's just a category error to say that if you think one set of values superior to another set that
necessarily makes you racist. That doesn't mean racists won't denigrate others' values for racist reasons (or that people aren't irrationally prejudiced towards their own culture), it just means that the word "racist" has a meaning that's widely abused.
Now, the people to the far east of Europe are entitled to think their own cultures (China, SE Asia, Japan, Korea, Tibet, etc) are very fine too, world class, and second to none. Africans and Amerindians are going to think their cultures are very fine as well. — Bitter Crank
Or alternatively, Europeans may prefer Eastern cultures and vice versa. I agree it need have nothing to do with race and if we go down that route we trivialize racism and make ourselves as irrational as racists who are also guilty of a category error in confusing biology and character.
