When I was growing up as a young adult during the time of this MISadventure of tv shows, we all thought Mr. Rogers was a queer and he sure did seem like one.  Either he was trying to hide it or this was his way of saying 'go screw yourself' but in a nice way!!

"Other leftists in the U.S. have been calling for “hate speech” laws for years to be used to quash the free speech of everyone who opposes the radical left-wing agenda.Sadly, Mr. Rogers himself, were he alive today and singing his little song about boys and girls, would be subject to destruction by the average liberal.The frightening fact of the matter is that we have arrived at a time when the left is so extreme in its hate for freedom and liberty that even someone as universally kind, loving, and even innocuous as Fred Rogers would be canceled by woke scolds."
