Well, just to throw another example into this, I'll be studying GLBT issues in psychology, so being in a department that has similar political views on gay/lesbian issues is essential to me. This is another area where personal feelings and religious views often influence academic work. Not to mention that, as a queer person, I wouldn't feel safe in an environment that didn't have an open mind towards the GLBT community. I don't think this is about avoiding challenge and simply having my views "approved and reinforced," rather I agree with those who are simply looking for an environment that will allow their voice to be heard, and not suppressed.
