There's just a very blatant anti-Arab/anti-Muslim bigotry that runs through all of their reasoning (as well as some people in this comment thread, apparently). People always talk about "hypocrisy" but that's basically just a thought-terminating cliche. When people engage in hypocrisy, it's because there is some other thought/ideology that they are using to guide their reasoning, and in cases like this, it's bigotry/racism.
