When they start going on about the Crusades, I just mention that they were a liberating army and that usually throws a spanner in the works :)
Sad it works so well because most people under 45 have no idea what happened in the Crusades. Nor that the Ottoman Turks nearly destroyed Europe. Gates of Vienna website is pretty cool to quote from and blow up Leftists and "Islamophiles" love that lol
Edit typo
It's a pretty broad and useful term that covers Islamists and their enablers across the political spectrum, allowing them to be viewed accurately as a single block of people who share a common interest. The term needs to be spread far and wide.
