Indeed RIP. A time when you could make non PC jokes and the public would (generally) understand it was satire rather than being outraged (although there was plenty of that too)
I think this is sort of reimagining history. The scripts were full of non-PC jokes because PC hadn’t been invented yet, either in the sense of not being a dick to people unnecessarily nor in the Richard Littlejohn sense of PC gorn mad I mean you can’t even racially abuse people with a different skin colour any more what is the world coming to I might as well be living under the third reich FFS
Also, although Mitchell and Marks (was it him that wrote the scripts?) had good intentions initially, I don’t think that the 40% of the total TV audience (or whatever) that watched it in the mid 1970s thought they were watching a satirisation of the prejudices of the white working class. I think they probably thought they were watching Alf Garnett take the piss out of the scouser and the “fairy spear chucker”. People didn’t object to it because that kind of language wasn’t particularly remarkable!
