Only if you... refuse to date, say a Chinese woman, who has beautiful looks, is a very nice person, in short someone you do feel attracted to (whatever that might mean to you) but you refuse to date her solely because she is Chinese. That is racism.
Keeping with the example... It is not racism if you don't feel attracted to Chinese women because, for instance, the general Chinese "looks" are not in conformity with your concept of beauty (and in this case we're obviously assuming, as an example, that beauty would be a major factor, but it could be anything else). The difference being, if it was a white girl with facial features you didn't like, you ALSO would not date.
