You beat me to it, but I feel the same way. Archie's character was written to be shocking so that people who watched it would go, "Man that guy is a jerk. I don't want to be like that", and then hopefully they would start thinking differently. Sadly, in today's overly politically correct environment, people who didn't know the history of the show and what the purpose is would start freaking out and complaining. I'm definitely not an advocate for being a racist or throwing around racist terms or even gratuitous swearing, but in some cases there is a reason and if you sensor it you have lost the whole point of the work being sensored.
I will agree with most here. The reason this show was so game-changing was it went where no show had gone before. Yes, some of the language wouldn't be allowed today, but in the early to mid-70's it was a critical component to not only change television, but change many attitudes about race, religion, sexuality, and gender....basically the same issues that are on every companies "non-discrimination policy" today.
To take this to a lighter place, I own most of the "All In The Family" library on DVD. I have rated all episodes over the years, and just for fun here are my favorites:
1. Class Reunion (season 3)
2. Sammy's Visit (season 2) guest: Sammy Davis Jr.
3. The Bunker's and The Swingers (season 3)
4. Archie The Hero (season 6)
5. Amelia's Divorce (season 5)
6. Maude (season 2) first appearance for her later spin-off
7. Mike's Mysterious Son (season 2)
8. Judging Books By Covers (season 1) first gay theme
9. Edith's Problem (season 2)
10. Black Is The Color Of My Lover's Wig (season 4)
