You need to pull his funds for college and see if socialism carries his sorry butt.
Why should he have to pay for his liberal son's indoctrination? What a great lesson in how the economy really works. Of course, if his son is majoring in "Medieval History", this will underscore it even more by pushing forward that day of reckoning before 10's of thousands of $$$ are wasted on esoterica. (I have nothing against, MH or any humanities, but one does need to perform his own cost/trade analysis on his nickel.)
