It's wild how if fewer than 10 people on the entire planet were removed from power, things would improve by magnitudes. Even factoring in any destabilizing effects. They're that fucking terrible.

The majority of organizing happening in Minnesota isn’t just peaceful, it’s INVISIBLE. Moms showing up who won’t be interviewed on TV, people whose ICE patrols don’t turn into viral video. The grocery runs, the donations, the people filming bc they happen to be there. Please remember this.

There’s some inaccurate NSF information spreading and causing extra panic. New increments on existing awards are paused. But: to the best of my knowledge, drawdown (reimbursement) on existing increments is not paused. ACMS is still accessible. Could change at any moment, though. Please share.
