1. In UUism particularly, we tend to think of everything in a Christians vs. everyone else, or a theists vs. everyone else paradigm. Actually, because the United States is so protestant-dominated, the real issues have often been protestants vs. everyone else. For example, public schools used to offer "silent bible reading time." The professor said that the protestants in the positions of power were so entrenched in protestantism that they found it difficult to imagine why any Christian could object to their child having a bit of time every day in class to silently read the bible. But Catholics aren't really into people interpreting the bible for themselves with no priest there to help them out, so they ended up siding with the Jews and the atheists and everyone else who tried to stop the practice.
2. In a discussion of homeschooling, someone brought up that she had a friend who works at a historic site for the War of 1812. Like most historic sites, it gets a lot of visits from homeschooling families. One mother asked the tour guide whether the War of 1812 was World War I or World War II and refused to take "Neither" for an answer. I've always supported homeschooling, though I wonder about the parent-teacher's ability to learn enough about all those subjects to teach them. I hadn't realized that standards are so low, at least in that state.
