There’s a hope that if you out-white the white people, maybe you’ll be safe. And the extremist right loves nothing more than a self-loathing minority willing to voice the master narrative. It helps then politically and it viscerally demonstrates ideological domination over a person.
For instance, a man saying women belong in the home as breeding vessels under the domination of a man is not as powerful as a woman saying the same thing. Roughly equivalent when it’s a racial/ethnic minority voicing white nationalist/anti-immigrabt/racist rhetoric.
The fact is, when you feel forced to choose between physical violence committed against you and/or your loved ones and structural oppression being enacted against the same, it’s not an easy choice.
It is the goal of fascism to attempt to replace political discourse with the rhetoric of real or threatened violence, which then creates the conditions where that seems like the only available options.
People toss around the word fascism haphazardly all the time, especially online. But this is fundamentally what it means: oppress yourself and/or consent to your own oppression under threat of violence.
