This is from Carolyn Hax's advice column. Gotta say kudos to this guy, this is probably one of the best ways this kind of situation can be handled.
Wow, that's brilliant. I think that older brother is a model to other bigoted, ignorant parents, modeling the very Christlike behavior that the parents themselves claim to hold themselves to
I have so much respect for the older brother. That's a remarkably dignified way to deal with such decidedly undignified treatment--be still my writer's heart, indeed. Kudos to him.
I wouldn't have lasted this long with a mother like that. I'd probably just stop coming to family functions.
