Of course you stupidly confuse his introduction of guests with his monologues. Two different things.
Carson NEVER dissed any of his guests with the possible exception of Barbra Streisand when she was a no-show because he wouldn’t change the seating arrangements.
Monologues were different. Whoever made a faux pas that day - be it a pol or a baseball player or Wayne Newton - was the butt of the joke.
Carson had no political point of view despite claiming to be a liberal. His two interests in life were comedy writing and astronomy. Not astrology, astronomy. He admired comedy writers out of all proportion and would often invite them to his home over much more famous people. His beach home was fitted with equipment that would have put NASA to shame.
WTF difference does it make if his gushing over commie Jane Fonda's treasonous actions during Vietnam were said in a monologue or intro??
If he claims to be a Liberal, I would take him at his word. Since I never watched him, it is immaterial to me.
