OP, as you can see, there's a lot of discussion around what this poster meant by segregation and what would be acceptable or understandable. No one here knows what she meant by "ensure our equality" either, maybe it was promoting separation ideas for black liberation, who knows. But you labeled them a reactionary, a liberal, a woke-segregationist, and compared them to nationalists etc

And you made a dunk tank post about it when it became clear that they didn't really want to engage with you. You could have taken a moment to get clarification on what they were saying, and if it really was a bad take you could have guided them, but instead your eagerness to dunk on them in the thread and here lead them to delete their account. Reconsider how you handle this, if you can't talk to someone here on chapo dot chat you're never gonna convert anyone outside of these spaces
