As a kid growing up in the 70s, "The Rifleman" was one the only other western besides "Wild, Wild, West" that I really liked--I envied Mark McCain and the great father he had on the show (played by Connors). Yes, each show was a morality play but so were many other shows of the 50s & 60s (including "Star Trek"). They made their point at a time when there was still some innocence in America, and even taught tolerance for people from other countries/cultures (for example, in the episode of "Rifleman" where a Japanese man gets insulted & pushed into a fight with one of the locals & uses Judo to defend himself). Lucas McCain taught his son by example NEVER to use a gun or fight unless it was self-defense. It sounds silly now, but when I was a kid I wished my dad had explained things to me the same way Chuck Connors did to his son in the show--ah well, thank goodness for TV writers! :)
