> and certainly didn't have a religion that promoted extremism Lets cut through the code words then and have a direct counterexample to what you're trying to say. Nigerians are primarily Muslims. They are also highly educated and among the most entrepreneurial immigrants to the USA. And while there's a "Nigerian prince" joke every now and then, they really are doing relatively well in the USA. Like, "better than Asia…
Ok, then what is the problem then? It's not racism; Nigerians are a lot darker than Arabs. Maybe it's a cultural problem, combined with religion: you never hear of Nigerian Muslims committing terrorist acts in the West. Islam is a big, big religion, and Muslims from some cultures simply don't have any kind of bad reputation (I'm thinking Malaysia here), while others certainly do. So maybe it is religion, just not the…
The sect of Osama Bin Laden was "Wahhabism", which is relatively rare outside of Saudi Arabia. And even then, the Saudi Princes who work with the USA are often pro-Wahabbism, so the USA can't even deride that sect (even if its the primary sect of Al-Qaeda). Because there's still "good guys" who follow that particular sect.
Note that the "Bin Laden" family was a very rich and entrepreneurial group of people. (https://en.wikipedia.org/wiki/Bin_Laden_family) Some of them were huge investors in the US before their "black sheep" messed up their family name forever.
The Middle East is complicated. Like, super super complicated. Honestly, the bin Ladens in general (aside from the infamous one) should be welcome to the USA. A bit unfortunate about their "black sheep" sibling.

Besides, if "Religion" was the problem, why did the USA DESTROY the only secular, maybe even atheist, group in the Middle East? (aka: Iraq Saddam Hussein and the Ba'athists).
Reason: the world is complicated. And thinking about it in terms of Religion only is a mistake. ISIS for example is a combination of yes, Wahhabism, but ALSO has the support of former Ba'athists.
And the Ba'athists believe in Secularism and secular law. They seemed to have joined in the ISIS fun not because of religious reasons, but because they wished to take over Iraq and saw aligning themselves with the fundamentalist Wahhabists as the best path forward and creating a unified Arab State.
So yes, we are fighting secular (arguably an atheist) groups in the Middle East. The world is a very complicated place. Yes, we have enemies some places, but Muslims exist across the entire world. You can't paint the issues of one region as a blight on all Muslims.
Even then: I'd imagine that we should welcome the many Iraqis who have helped the USA and are now getting targetted by ISIS in their country. We have friends in the region and we are turning them away with our immigration policies. We've turned our back on our closest supporters of that region, and I wouldn't be surprised if a large number of them have died because of their pro-US support or actions.
TL;DR: Immigration policy is hard.
