The end of Freedom of Speech and Religion.
Islam is a totalitarian ideology with a political imperative, that is violent, coercive, repressive, and supremacist. It should not be treated as a religion until it reforms itself.
Islam is, was, and ever shall be our implacable enemy. GWB's fatal PC naivete and cowardice in declaring Islam the religion of peace has completely disarmed us.
Self preservation dictates that we do what is necessary to defeat the enemy. The threat posed by Islam is no different than that posed by Nazism, and should be treated as such.
One cannot incite to riot, murder and violence as speech. Murder, violence, and oppression are foundational to Islam. It must be pulled up, root and branch. It must be rejected by the West.
There is no 1st Amendment in the UK. There are a number of strict limits that would surprise Americans - it’s sounds to me like the government may just start exercising their prerogatives.
