Random thoughts.
One thing I always recommend is to look at the people who are really driving a particular movement/narrative. Are they look like the people who they claim to be defending?
Remember that it was the centrist/moderate "wing" of the Democratic Party that originally sought to extinguish the influence of those who practiced identity politics. They been playing that card for YEARS, and did so over and over against Obama.
Now they are using it as a weapon. The irony!
I'm not going to get into a back and forth about what role identity politics should play in the future of the Dem Party. People's personal experiences are so different it's more likely we end up talking past each other than anything else. But ideological purity is NEVER a good idea. Always ends up in failure at the polls. Now, going back to my first statement - when you see the people who are pushing this kind of purity, very often they are immune to the repercussions that come with losing. My ex girlfriend was in the middle of a PhD program and thus was very active at her university (where she also taught). She epitomized the social justice movement, and she taught me a lot about how and why they frame certain issues in particular ways. And it gave me a more nuanced understanding than people who reflexively oppose any idea proposed by a person/group branded as social justice warriors.
But the one thing I always mentioned to her, and which she begrudgingly agreed, was that although she was black and did not come from a privileged background by ANY means, she was NOW in a position whereby no matter what happened at the polls her position was secure. She had the right degrees from the right universities and the right network that ensured she would continue to thrive no matter what happened. That will cloud your judgment and unfortunately it's something I see on both sides of this argument.
