Russ, I see it (PC) as a development of the strident feminism that started and gathered pace in some US universities (I read Playboy during the epoch) and, as far as I could make out, was a perversion of the norm, which has always identified itself to me through the fact that women worth a damn are born with the skills to get anywhere they want to get. Dammit, they come with a natural advantage over men or, at least, gentlemen. Dealing with idiots they can never win, feminists or not.
My own wife was never into that feminist camp, yet she held the respect of anyone who had to deal with her; all that a person of either gender needs is an education. That should provide them with the understanding of how to live and how to get what they want from life. Largely, you get back what you sow. Attempting to change the laws of nature are futile at best; I wonder how many lives and relationships have been ruined in the struggle to have it all.
But, as with so much, the 'movement' spread outwards and across the world. Some intellectuals must carry a heavy load of guilt and regret.
