Liberals marinate themselves in a stew of entitlement seasoned with victimhood.
I actually did a study on that, being a Galluadet alumnus, that the campus is more liberal than conservative. Even Clinton was there to give a commencement speech for the graduating class of 1994.

Over the years, it had become progressively more liberal. No kiddin. And what was their rallying cry on the campus of Gallaudet University?
with a deep and gravelly voice:
Oppression!
Audism!
Not fluent enough to sign in ASL.
Etc..
(make one up here)...
With all due respect, this is not entirely true. There were also true and valid concerns about the way the grammar and high schools were being run; for example unqualified teachers and dismissal of the parents concerns, such that - they moved their kids out of the school. So there is more to the story than the MSM is reporting.
"identity politics"
Ever notice how liberals love to stereotype and/or categorize people? I've known tons of liberals and nearly all of them think in terms of identity politics as you so aptly put it. They have a very difficult time dealing with people who don't fit neatly into their little boxes.
