Is there any theory as to why the Left embraces Islam to their own destruction?

As someone who identifies more with the democratic party than the republicans, and someone who is for restricting muslim immigration, I think The_Donald is greatly exaggerating how positive the left is to muslim immigration. Critizing Trumps latest tweets has little to do with being pro muslim immigration. There is so much more wrong with the tweet from the president of the United states (a title most of the world is holding to high regards).

Here in Norway, youll find anti-immigration sentiments on most of the political spectrum, except the far left parties. Most of right wing parties here could still be said to be left of the democratic party's views.
