I'm not sure your conclusion follows. I tend to reject identity politics because of its Marxist associations, and I don't think Marx's analysis and solution to ecomonic problems ever worked. I wonder if identity politics and intersectionality are being used to stir up problems rather than solve them - the proletariat has not been good at producing a revolution, but if you make enough people discontent with being 'oppressed' then you might yet get somewhere.
Wow that's quite a reach - you don't like the idea of anti discrimination policies because a few (but by no means all) people who fight discrimination identify as Marxists.
Identity politics certainly do stir up 'problems' or rather difficult feelings amongst those who would rather that discrimination was allowed to continue, and don't like it being pointed out.
Once something like true equality is achieved we'll no longer have a need to fight this unjust discrimination.
Until then, there's a job to do.
You don't feel or experience this discrimination or oppression that you rather dismissively put in inverted commas because you are, I am guessing, a white man.
One of those people who, even if not actively involved in oppression, has certainly existed all their life in a world that doesn't unfairly discriminate against them because of their particular skin colour, ethnicity, or sex.
Shep here has picked up on identity politics by complaining about white men having to jump through hoops. White men are classed as the oppressor, but unfortunately not all of them are or were.
No one ever said they are or were 'all oppressors' - You just keep saying that people say that, as if to claim some sort of 'victim' status for white men.
The point is that
not being white or male imposes disadvantages that need to be changed if we actually care about equality. That includes the words we use.
Like I said above you've probably not experienced that disadvantage directly, having always been white and male.
Of course a good way of signalling that you really don't care is to dismiss it all as rubbish.
But there is still plenty of discriminatory words and speech used, that come across as really not giving a toss about discrimination such as racism.
Such as the incident that sparked off this thread.
