This one at the University of California encountered the reality of identity politics.  It collapsed into, as one of the conference-goers called it in her op-ed for the UCLA Daily Bruin, an oppression Olympics.

From the first link:

In one of the larger workshops, one of the students raised a question about why the only issues being discussed were those involving anti-blackness, prompting an African-American student to respond that black students are the most oppressed, to which a Muslim student made a comment about her people being bombed in the Middle East[.]

And

Above all, conference participants each wanted to focus on their own particular minority issue[.]

And the whole thing apparently turned a series of microaggressions, unsafe safe spaces, and canceled workshops.  UCLS student Robert Gardner:

I am very unhappy about how this conference was ran. There needs to be accountability for the trauma some of the organizers made. And I didn’t appreciate my workshop being cancelled….

Apparently grammar isn’t a safe space for young Master Gardner, either.  But he continued:

It was really hurtful to have other marginalized identities silenced because a small fringe of organizers decided that their oppressions are more important (talk about Oppression Olympics. …)

Stop oppressing me with your superior victimhood!
