That reminds me of my great-aunt and great-uncle (I have no genetic aunts or uncles, so they kinda fill that role for us) - I always knew they were homophobic, based on how badly they dealt with their gay son's death from AIDS, but I had no idea they were racist until one day I was talking about a cute Japanese boy in my class and my aunt said, in genuine horror: "Don't you go bringing him home!"

To my uncle's credit, he turned around and barked at her, "SHE CAN BRING HOME WHOEVER SHE WANTS." But it was still an awakening. I don't see them much these days - at some point, I just became unable to smile through the ignorance and knew I'd lose my mind if they blurted out something unacceptable in front of me.
