Identity politics - when it was a good thing - were an idea that you can be anyone you want and nobody has the right to tell you what to be. It can be described as a raw diamond.

Leftists organized it and put it into uniform, but while everybody remembered it is a good thing in its essence, everybody would support that (or fight only the ordered and neutered version, not identity politics in general). Also other leftists, not trying to do that, still wouldn't understand the implications of that kind of change.

Now the difference simply can't be ignored.

It's a flaw of leftist ideologies - classifying everybody into groups with group interests. Reality is very easy to describe this way, a bit like what Russian school history student books are. However, such descriptions are useless. They don't allow you to synthesize anything. Just to say "that grew there".

Good methods allow predictions, while this one allows only describing the past.

TLDR identity politics is a thing in itself now
