What are the chances of my relatives shunning me?

i was wondering what the chances of my relatives shunning me for being bi would be. they're "average americans," meaning white, middle cl, and christian. they don't like illegals, really rich people, the japanese, muslims, or gays. once my aunt said the only good thing about gays is that she thinks they dress nice. they also don't believe in gay marriage. do you think they'd be able to see past their ignorance and accept me, or should i wait for impending doom? i also don't have an amazing relationship with them as is.
