One thing I like about Sikhism is finding out, okay, there is this monotheistic religion other than Islam, Christianity, or Judaism, which has about 20 million followers worldwide, and which I don't really know much about.
And then there was this fascinating court case. As I understand it, Sikhs wear a kirpan which is usually a small knife on the belt symbolizing that they are protectors and defenders of the poor, and this conflicted with IRS regulations against its agents having weapons. Now, to further complicate matters, Sikhs generally view the kirpan as a symbol, and not as a weapon. This has to be one of the greatest religious liberty cases of all time, and I don't know how it came out!
