Bill Warner’s most excellent site, Political Islam, produces regular reports on persecution of women, Christians, and other groups that Muslims like to intimidate and ethnically cleanse periodically out of lands they control. I try and republish when I can but often his emails get buried. It is well worth going over to his site and subscribing to those mail outs. For those who do not know of Bill Warner check out this truly stellar speech he gave in Tennessee with German subtitles.
Bill Warner talks about Banu Quraiza -- a Jewish tribe which was annihilated by Muhammad. I wrote about this over five years ago: Banu Quraiza or How the Prophet Muhammed Momentarily Forgot the Peaceful Nature of Islam.
