They are "oppression fleas." Many label themselves "allies," so that they may also grab a share of the victimhood/grievance pie. You simultaneously have the "Oppression Olympics," where a hierarchy develops of which group of oppressed people is most oppressed. So, for instance, while white women are oppressed, they are far less oppressed than black, lesbian, transgender paraplegic Muslims. Your one way up the victimhood pyramid is by glomming on to one of the higher-ranked groups.
I think I can sum this like this:
1. Fixating on identity and "lived experiences" is a self-absorbed pursuit. It isn't puzzling why these folks are thus so obnoxious.
2 Our subjective experiences are often distorted from reality. This is something folks like you often recognize in "white males" who believe themselves oppressed. Trust me, it happens often with non-white males and their belief in their own oppression and suffering, as well.
3. Fixating on our identities divides rather than unites people.
4. Aside from child abuse victims and victims of human trafficking, no group in this country is "oppressed" by any historical nor any current standards, relative to other societies.
5. Projecting and celebrating fragility, weakness, demanding safety be placed above all else, produces weaker people who, in turn, manufacture oppression and grievances to sustain the angle they've contrived. That's essentially the modern civil rights and the modern feminist movements. They long ago ran out of legitimate discrimination to protest and are left with either trivial "problems" that aren't problems or concocting immense conspiracy theories about cops deliberately targeting black people, or judges, prosecutors, school administrators and teachers conspiring to suspend and expel black students, or men conspiring to pay women less money, implicit bias, white supremacists on the march, et cetera. Is it really any wonder we now get hoaxes exposed on a daily basis from these folks?
