And the mayor of your biggest city is a muslim.
So what? AFAIK, Sadiq Khan has been doing a superb job for a while now. You can never completely eliminate all the crimes when your population is close to ten million.

So you have literally surrendered to Islam. Quite aside from the rape rings that have been going on for DECADES. That sort of thing doesn't happen for that long with cops who are afraid to be called racists without some very high level people involved. Your supposed leaders are traitors and the people are idiots.
Your point ain't making much sense to me. Mayors are elected to make the overall infrastructure better, which includes the improvement of the system of transport, housing, policing, etc. If a Muslim mayor is able to handle all this in a good manner, why the hell should anything else (including religion) even matter?
You can never trust a muslim, the koran gives them the right to lie and manipulate any and all infidels in order to promote islam.
They literally have a word for it too. It's a core part of their religion.
Additionally, the Prophet was a perfect being who any muslim should strive to emulate. He is flawless and must not be criticized.
He married a six year old girl.
This means that muslims support or at the least do not oppose pedophilia. Anything else would be haram.
Western governments had understood the danger of Islam, and it's focus on spreading the religion through infiltration and war. This was well known throughout the civil service and the highest levels of government. However this understanding was either forgotten, or deliberately ignored by our governments in the past 40 years
It is clear infidels are to be killed or forced to submit to Islam by Muhammad, who is considered the perfect example of conduct. Hence we see ISIS copying Muhammad in his killing-sprees, rapes, stoning, child-marriage, slavery... and all manner of other unpleasant things that Muhammad got up to. We should all be concerned about anyone who believes that this is the perfect and unalterable word of god (and many really do, which is idealogically why the segregate. One of the major issues with Islam appears to be that Muhammad had a peaceful phase when he was in a minority, and then a violent death to unbelievers phase when in a majority.
This means that in countries where Muslims are a minority they can copy Muhammad and behave peacefully. But if they reach a majority, history suggests that they may feel compelled to follow the instructions from Allah and turn to violence.
