I went to the Emerald City Antifa site on YouTube. I didn’t see any posts on it more recent than early 2021. It makes me wonder if Antifa/BLM were mainly founded to create a sense of anarchy and chaos during the Trump years so as to harm Trump and weaken his chances for re-election. No wonder Merrick Garland and the DOJ regard them as allies.
I would agree with your assessment.
