So now we should have an immigration requirement based on religion??

Well, no one expects the Spanish Inquisition!

Since all you know is what you see "popping up", you have no knowledge of Muslims who live their lives quietly and assimilate into the societies where they live, because they don't "pop up". So they have their own religious practices -- so what? Isn't that what America is supposed to be for?

Let's re-examine your post:

I wasn't looking for them. They popped up all by themselves. And I don't see anything else except adversarial behaviour from europeans in general. They are here as immigrants because they want some of the good resources that our country has created. But they don't share native values, and even define some of the words differently. They don't understand that the pre-existing culture was responsible for conserving those resources they so covet. And the culture of their homeland is responsible for the war and poverty there they are trying to escape by coming here. So, I don't agree with you. I don't think devout puritans should be allowed in.

But he didn't think like you, in spite of the fact that he was kidnapped and enslaved by Europeans before escaping back to America. So now we have a melting pot -- except, of course, "No Muslims Need Apply".

America has survived bigotry before, and it will again. Open your eyes and look around. Hatred is the enemy; you are serving in its army. Go AWOL.
