It’s ok to not agree on everything. Keep a good relationship. He will mature.
I agree, don’t worry about the Ron Paul thing.
I can see why some young conservatives might be attracted to Ron Paul for now. But he is getting a good grounding at Hillsdale and with a little maturity later one he will be fine. Also, much better to send him to Hillsdale and have to hear about Ron Paul now than sending him almost anywhere else and then having to deal with him being a total liberal forever. AFter all, Ron Paul is actually right on some things. Liberals are wrong on just about everything.
