Jihad Watch is a web site by Robert Spencer. It has a lot of information, as well as the typical discussions that occur on a site.
He also maintains the parallel site “Dhimmi Watch.” If you don’t know that word, it is worth your time to take a look. In conjunction with Daniel Pipes’ bibliographic site (linked under International/Military), you can get yourself a pretty good education on Islam.
Americans tend to view religion through Christian spectacles. Islam is not what most of us would consider to be a pure religion. That is, Mohammed put together the Quran as a religious and governmental guide. In fundamentalist Islam, the Church and State are inseparable. In fact, they are a single entity. If they were to be separated, both would die.
Don’t just take my word for it. Take a look at these links.
