I mean, they obviously hate “illegals” too and most of them, anyone who isn’t white, but whatever. There is a large difference between hating Islam and hating Arabs, and they all seem to hate Arabs and call them slurs. Like, people hate Christianity, which a lot of white people are, but most of them likely don’t hate white people.
There is a belief that there is a “civilizational struggle” and especially for our context between the Christian West against the Islamic world. So the Iraq war is viewed through the lens of a kind of 21st century crusade, for example.
When it’s cast as “civilizational” like that, race and religion gets conflated - so the assumption is that all white people are “Christian” at least in some larger cultural sense if not on an individual / personal level, and vice versa that all Arabs are in some sense “Muslim” even if they’re not individually.
It’s basically just racism, as far as I can tell.
