have you tried reminding them that you are entitled to your views?
if they sill deny you yours; ask them how they would they feel if you didnt acknowledge theirs.
if your family truly abandon you because of religion i would say you are probably better off without them, though i hope this is only your impression and that the reason they might tear into you, especially if they are devout christians, is because they love you and cannot understand why anyone would deny the religion you were brought up with.
