Actually, Austin is pretty liberal. One graduate I know said the way to resolve the problem with Islam is, "stop making them angry with us". This is typical of academia. It is not the wearing of the scarf that scares people, it is the insistance on the part of Islam that their customs trump US culture that pisses people off. If people are worried about terrorism they only need to recognize that most terrorism is the product of Islamic mentality. And as for profiling, we should do that too. If we know who may be a threat, they should be subjected to careful review. Its not that hard to understand either.
The point in the article about profiling at airports is so off the mark, it's in fact the opposite. The little old grandmothers are profiled instead of the shifty middle-eastern males.
