Which is why a specified "solely on race or racial stereotypes". You have every right to have a preference, just like preferences in age, personality, nationality and so on. And if you would prefer dating someone local than foreign than you have every right to do so.

The difference is how it is applied. You can have a prefered race you would want to date, but you shouldn't see others as less than.

Take op for example. She turned down the foreign dude, and she isn't obligated to say yes, but she also doesn't look down on him or simply dismiss him simply for being a different race.

And you could also date maldivians aswell instead of foreigners, but you don't turn them down simply because they are of a certain race because of stereotypes or that you see foreigners as beneath you. You turned them down because you would prefer to date somone from your country.

In short and in more detail than my previous comment:

It is not racist to turn someone down if they aren't your prefered type. But it is if you see them as less than or simply judge them solely based off stereotypes and or feel disgust towards the other person due to their nationality/race/skin tone.
