David Duchovny's parents are both professors I believe. I know Duchovny's dad was a liberal. Before there were "Quaylisms" or "Bushisms", there was the "Collected wit of Spiro T. Agnew", that was a compellation put together by Duchovny's dad.
Look, you might be DD, so I'll be diplomatic. You can find one or two "thinking" and fully functioning actors, but there are not alot of them out there.
