And what they drink at communion.
I think a lot of people who aren’t involved in organized religion have an inaccurate view of how people in these denominations actually think. It’s a mistake to think that all, or even most, of the members of a religious group agree with (or even understand) the doctrines of that group, and this is even more true with respect to the political positions taken by the denomination. My own denomination, United Methodism, has a bunch of positions on social and political issues, and I would wager that only about one in 50 Methodists even knows what they are.
