I agree that there’s ways to do representation badly, but especially for interracial couples, you’d probably have to go back quite a few decades for examples.

Lol, tf? Are you from the 1950’s? “Too much gay stuff” is at least a semi common complaint still, even if unjustified (I’d be more open to “uses gay stuff badly, is flat and stereotypical in it’s depiction”), but “too much race mixing” is something I’d think no one but a bona fide segregation advocate would say.
