If you don't want people to know and don't want to make a weird scene out of it, just say something like "it's complicated" or "I'd rather not talk about it". Or if they ask where you're from, you can always answer with some other place you've lived that wasn't your birthplace. Most polite people wouldn't ask you anyway and hopefully those who do will get the hint and not prod any further. If you say "raceless", it'll probably either get a "uh, ok then" kind of response from people who don't really care (bureaucrats who just need to fill out a form they have no control over), or you might invite a discussion like "what's that? what do you mean? where were you born?" Do you want to have that convo? It's probably not going to go anywhere useful outside of controlled contexts like academia or a group of friends. Race is a pretty taboo topic here in polite contexts between strangers. On the other hand, if you really want people's unfiltered thoughts on your race or lack thereof... plenty of places online where you can spend a lifetime arguing over it. Not necessarily a good use of time, mind you, but people will definitely have opinions...
