To me, you are either Christian (following the teachings of Christ) or you are something else. It doesn't matter to me what denomination people want to call themselves, as long as they don't try to let their religion influence politics and social norms. When I was a kid, my family jumped back and forth between Presbyterian, Methodist, and some other church I can't recall, depending on where we lived at the time. It wasn't really about the doctrines those denominations embraced, it was more about convenience.
