I don’t think anyone is prepared for what they just did w/ ICE.
This is not a simple budget increase. It is an explosion - making ICE bigger than the FBI, US Bureau of Prisons, DEA,& others combined.
It is setting up to make what’s happening now look like child’s play. And people are disappearing.

I've been banging this drum for years now, I know, but Zohran's Big Night is a clear illustration of the power of giving people a vision of the future that boldly contradicts the rhetoric of Republican fearmongers. Not just "disagrees on policies," but actively paints a different image of the world.

Back in the mid-20th century, the FBI could place an individual under surveillance solely for being LGBTQ. This is what enabled the anti-queer witch hunts of the McCarthy era. Now, DHS permits surveillance of LGBTQ people again. Just being queer makes you a suspect. www.advocate.com/politics/dhs...
DHS quietly eliminates ban on surveillance based on sexual orientation and gender identity
The DHS quietly updated its policy manual earlier this month, removing LGBTQ+ identities from the section prohibiting surveillance based solely on immutable characteristics.

What does it mean for something to be Turing complete?
I answer this question, and more, through a series of fully interactive Turing machine simulations! Play, pause, step forwards and backwards, and even write your own Turing machine programs in my latest blog post.
