there is a difference between saying "you're not welcome here" and saying "we do not have the infrastructure in place to accommodate your request".
i'm not happy about letting in religious people, don't misunderstand me. there's lots of people i'd look in the eye and tell to take a hike.
but, that's only half the crisis in front of us. and, even if 100% of these people are wonderful egalitarian leftists, there's still nowhere to put them at the moment...
