Islam is by nature an invasive civilization with the goal of world domination. The Far Left and Neo-Conservatives who currently approve of NO Borders, MASS immigration, selling our western nations to the world like whores, and attacks on our freedoms of expression - they will be caught between patriots and invaders in the coming conflict.
This has nothing to do with Christianity, for Islam has the goal of subjugating the entire world under Islam. Those Far Left who dominate western universities, media, and government will be forced to choose sides in due time. The traitors are already under the pressure of being exposed thru the Internet. Old Media can no long deny and conceal these realities.
As I recall, the mayor of London said nothing about turning London into an Islamic state. This above is nothing more than your fear of foreigners and I'm willing to bet your fear extends far beyond just Muslims. It's pretty clear what you believe is a nativist agenda, and as such, there is no reason to continue arguing with you.
He has called westernized Muslims "uncle toms" in the past and has shared speaking platforms with pro ISIS speakers. While I will give the guy the benefit of the doubt he has changed since he was obviously able to convince London to elect him (but Europe does seem to be intent on cucking itself so maybe not). Past behavior hasn't done anything to disprove the stereotype.
