Sorry to hear that, but its been my experience that a friendship that gets tripped up by relatively superficial differences like that is probably not a strong friendship to begin with. I am not old, but the older I get, the less I feel like religion and politics are relevant to a person's personality. At the risk of trivializing them too much, I almost think of them as a team allegiance like rooting for the Packers vs the Steelers... While there are consequences for what people believe, in terms of a friendship, these things really don't matter to me.
