Wow, you have the inside Hollywood scoop... I liked Don Knotts, please don’t tell me any more :)
I have never watched Ron H. movies, that I can recall. They just didn’t interest me. So, he was off my radar I suppose.
I do know about a few “closet” conservatives in Hollywood, lol. Maybe not so in the closet, and maybe not sooo conservative, but still...
One of those conservatives you indirectly mentioned is Chuck Norris, I believe.
Just spoofing about Don Knotts.
Tom Selleck is one of the Hollywood conservatives.
