At National Review Online, Todd Zywicki has some suggestions for alumni who feel they need to give to their alma maters even though the school may be run in a way that indoctrinates the students in the Politically Correct view and shuts out other viewpoints. He suggests various ways to target or withhold donations to achieve more diversity of viewpoint.

At the end, he suggests that donors need not necessarily give to the school they attended. If your old school is hopelessly in the clutches of the PC crowd, give to another school that is not.

Going one step further, you can always donate to an advocacy group that is focused specifically on promoting a non-PC position.
