If you haven't attended a Muslim sermon before, here is a good one to start with. No hysterical ranting about "death to the Jews and Crusaders," no talk about decapitation, but a lot of discussion about...well, it wouldn't be lady-like for me to say. See the MEMRI clip here,

This one is pretty typical. The Muslims will conquer Rome, Western Europe, then the two Americas and "even" Eastern Europe, etc, etc., not just by force, but by conversion as well.

It's important to watch this stuff from time to time, just to keep reminding yourself of what, sometimes, you begin to forget or may not quite believe can possibly be. Friday Sermons  -- the khutbas -- are a vivid reminder of what Islam inculcates.
