Its GOOD to know the language of your enemy!
The dept of homeland security is paying very well for translators, it makes sense to know what your enemy is saying, if no one learns their language, then they have a secret language to communicate in.
Yes everyone should read the koran, KNOW your enemy, dont let anyone tell you whats in there, read it for yourself....warning though, its like the twilight zone, ramblings of a madman.
I wouldnt watch their sites or shows, I have no desire to see what kinds of things they like on TV.
