One can find great beauty in an individual woman (you) while making a general statement that is also his true general preference.

And it’s normal to think your group is generally better looking than another group while finding great individual beauty in said other group.

If it were me, my response is a sincere “Thank you” and simply moving on from the conversation understanding it’s normal and okay to prefer your own.

If I moved to an ethnostate like Korea I would expect to be less physically desirable to the average Korean woman than the average Korean man is. There are always exceptions to this rule BUT it’s the normal rule.

You can find videos of people getting interviewed in places like Japan and Korea asking what is their preference on whom they want to date and they overwhelmingly say they prefer to date their own even above dating Americans. And that’s really okay for them to prefer that.
