“He’s married to a black lesbian.” (How do you know she’s black?):)
You say that like it’s a negative thing. Ha ha!
No, but seriously, how do you know she’s a lesbian?
I believe she used to be a lesbian rights activist.
From Wikipedia:
McCray published an essay in Essence in 1979 entitled "I Am a Lesbian". In that essay, McCray "frankly discussed her sexuality and expressed gratitude that she came to terms with her preference for women before marrying a man".
