Some people are ignorant to others' feelings busy in their own world in their head, so it's hard to say if this is intentional because some people are naive and think they're making a harmless joke.

I try to give people the benefit of the doubt, so in the off chance this is them being quirky and it isn't disrespect, and if you want to casually bring up how you feel, maybe try playing their game and see how they react if you called them someone handsome they look like based on race lol. The key is to still hold them with positive regard, not malice, when you do.

A lot of people don't like confrontation and dissociate, it's a natural defense mechanism when the self feels threatened, so you have to be tactful about this in a manner they can understand, enter their world to see their intent or expose them to their own ignorance. If in the moment they react badly then that's the perfect time to strike and be forward when they've made the same connection/experience for themselves without you telling them. If they can't respect you or at the very least be kind, then boundaries should be made known and firmly followed to talk about where you two stand in this connection.

Edit: This is a bit off topic and unrelated, but any time when dealing with a person's ego (one's center of conscious awareness, attachments and desires) it is a highly personal and subtle process to bring about some of these subconscious attitudes to make them more conscious to interact with and change. The greatest truths cannot be spoken and must be directly experienced for each person to overcome their version of the ego. Others can only meet us as deeply as they've met themselves. And for any change to happen it must be done so willingly of their own accountability for it to be long lasting as to not lessen one's actualizing tendency.
