I get angry all the time. I have a terrible temper. I come from a long line of brawling, angry Irish. All those stereotypes? Pretty much true. However, I am a 21st Century kinda gal, I live in the civilized world, and I haven't been in a physical fight since I was 15. Fact of the matter is, I know that if I want to live in this world, I have to play by its rules.

Therefore, I really don't give a rat's arse to hear about some Mick-turned-Muslim talking about how angry he is, and how the West deserves what it's getting.

His name alone gives a clue to the conflicting cultures he embodies. Now a London resident, Kelly is Irish Catholic by birth, Muslim by choice. He was an altar boy growing up in Dublin who went to Saudi Arabia several years ago to work as a nurse.

Kelly spent three-and-a-half years partying and carrying on before he landed in prison for brewing his own alcohol, which is illegal in Saudi Arabia under Islamic law. In prison, Kelly embraced Islam, took the name Khalid, and came out -- by his own account -- a changed man.

Fast-forward almost five years, and Khalid Kelly is an angry man. Angrier now, it seems, than he was a year ago, when four young British Muslims brought their holy war to central London, killing 52 people and wounding 700 in four suicide bombings on the city's transit system.

In Kelly's circles, the London attacks were justified, and the belief is that attacks will continue until Britain withdraws its military from Iraq, Afghanistan and everywhere else in the Islamic world.

"What happened on 7/7 is a direct consequence of British foreign policy," Kelly told my colleagues Nic Robertson and Paul Cruickshank recently.

Kelly used to belong to al Muhajiroun, a Muslim group branded "extremist" by the British Home Office after two young British-born Muslims who attended Al Muhajiroun meetings went to Israel to become suicide bombers. One succeeded, blowing himself up in the middle of a Tel Aviv nightclub.

Al Muhajiroun disbanded in October 2004, and its supporters went on to form several new groups. Under the umbrella of the Islamic Research Group, they just released their own report on 7/7. Not surprisingly, it echoes Kelly in blaming the British government -- and moderate Muslims who collaborate with it -- for what happened in London on 7/7 and for what it calls the current war on Muslims.

Kelly is blunt about how Muslims should respond.

"[Islam] is not a religion of peace, it is a religion of war at the time of war and peace at the time of peace," he says.

Lock the little bastard up. Before I get too angry...
