The majority of British muslems have not read the Koran either, because it is in Arabic and they cannot read that. So they get their interpretation of the Islamic scriptures from Koranic scholars. Unfortunately tthe majority of these scholars are based in far off lands and do not understand our culture, and the interpretations they make are flawed to say the least.
The Red Mosque incident is more to do with Musharraf desperately trying to cling to power than of any great religous significance. If there was an attack on the authority of the rule of our government in the UK, the target of authority would not be a mosque, so it would not happen here.
The Bible, Tanakh and Koran are virtually identical in their early rendition (old testament story) of the history of the world. This is where in each book most of the smiting and killing and barbarism takes place (all in the name of God, Allah etc). If you can condemn the Koran, then you must concede that the Bible and Tanakh are also condemnable.
