Islam is incompatible with western civilization and western values. And we should limit and discourage Muslim immigrants for that reason.
I've read many over-the-top insensitive and foolish pronouncements regarding Islam on this site, but your quote above is not one of them.
On the contrary, your sentiment is entirely reasonable and logical.
Islam, at least in its stridently authoritarian, fundamentalist form, is indeed incompatible with Western civilization.
As such, any Muslims who live in Western civilization must adapt accordingly to the open society in which we live.
Conversely, any Muslims who wish to impose their absurd Tyrannical worldview upon the peaceful People of the West should leave, or be forcibly expelled.
People can believe whatever they want, but they are not entitled to impose these beliefs upon others by attempting to destroy our (at least marginally) Free society.
But history has shown that the number of Muslims must be kept at a certain level or below, because past a certain point, they become uncontrollable.
