My father was a Catholic, but my mother wasn't. She had to do that weird deal you do as a Catholic - they deign to sanction your marriage and you have to bring your children up as Catholics.
Religion is interesting because it brings out the best and the worst in humanity. It can be a source of good deeds, whether it's people from different spiritual backgrounds coming together to help other people in need after a crisis. But it's also a cause for war and bloodshed.
