I’ve heard that people are often interested in Asian women because they are expected to be subservient. I just think that while women of any ethnicity can be good-looking*, East Asian women are better-looking on average. I wouldn’t call that a fetish the way that you do, and I don’t think it’s somehow worse than a preference for any other sort of physical feature (which I wouldn’t call a fetish either unless it was very extreme).

*Good-looking to me rather than in an absolute sense.
