Don’t be afraid of ICE, don’t be afraid of Trump. They are clowns and cowards. If enough of us stand up to them together, collectively, we win and build a more beautiful world on the far side of all this

Stop calling this an “administration.” It’s a fascist regime.
Stop calling Trump “president.” He’s a dictator.
Stop calling ICE “federal agents.” They are the gestapo.
We need to collectively wake up and rise up

While escorting a defendant out of immigration court at 26 Federal Plaza, Brad was taken by masked agents and detained by ICE.
This is still developing, and our team is monitoring the situation closely.

My latest substack. Two main points:
1. The media needs to stop mincing words. The way journalists aren't straight up calling this fascism reminds me of the decades-long media failure on climate.
2. Stay and fight, hard. We can still stop dictatorship open.substack.com/pub/climateh...
