So, I think about race relations, as a somewhat obvious example.

The impression I've gotten is not that LW is capable of an advanced discussion of race relations but not of gender relations, but rather that race relations simply don't come up in conversation as often as gender relations do. (Which isn't too surprising, given how much more fundamental gender-marking is to our language than race-marking. )

But perhaps I'm not giving the community enough credit. If there have been valuable discussions here about race relations, I'd be interested to read them... pointers are welcomed.
