'Politically Correct' has become a slur, if you will, of the far right resisting the inclusiveness of progressives. It's a loaded term.
And Jamie; Rose was meant to be a working class London girl; although Billie Piper is not.
To paraphrase Alanis Morrisette, Rose Is not the Doctor.
Many many companions have been Londoners.
‘Politically Correct’ has been a term for criticising all sorts, and doing all sorts...rumour has it that it was originally supposed to be a form of subtle sociological ...well, terrorism I suppose, in its mildest form...invented by the ‘left’ way back when. Like Cold War or earlier way back when. This of course may be true, or some right wing propaganda.
I do find it an intriguing little sentence, the idea of something not strictly correct (or true) but it is political (i.e gets you liked/voted for) to treat it as such. Or that it is correct in a given political circle, whilst not given a figgins about elsewhere, possibly where it might actually matter.
Otherwise we don’t need the couplet do we?
It is simply correct that men and women are paid equally for performing the same job, no need for ‘politically’. The appending of the word can make a lie of anything, because hey, politics.
Problem is, it did seem to start out as sort of policing... ‘you can’t say that it’s not politically correct’ which then got picked up by people saying something mildly unpleasant, or worse, or sometimes just a faux pas ‘ooh I can’t say that, it’s not politically correct’. Soon comedians could just say the last bit and let the audience giggle at whatever they made up their head.
Then you get the nostalgia phase ‘couldn’t make that these days, it’s not politically correct’ about some stuff that frankly shouldn’t have been made then (or in some cases, would not be made today because well...it isn’t politically correct...even if those with nostalgia don’t get it. I mean I can’t stand seventies sit coms, but they are not always quite as people remember.)
Now we are back at the tribal war stage of its use.
But as I say, there is a difference between it and equality.
We have great fun with the idea of ‘political correctness gone mad!’ Over here. Sometimes it’s mildy right wing grumpy, sometimes it’s actual right wing grumpy, more often than not it’s just some affront to common sense done with a hint of jobsworth, and quite often, it’s a load of bollocks...one way or another. These days it sadly descends into frothing looms fighting over something quite often unimportant...sometimes humorously related to health and safety (which seems a closely related area.)
Little things like ages spitfire pilots not being allowed to get in the planes again on anniversaries, because it would be too dangerous...which as you can imagine leads to a smirk from some old chaps (and a very famous few chapesses) about the safety considerations last time they had to get into one.

It seems it was not right wing propaganda, unless there’s something I don’t know about Brittanica. (Ok, there’s lots of things I don’t know about Brittanica, and between Disney, Ford, and Marie Stopes, nothing surprises me anymore...but I don’t think Brittanica are right wing.)
