MAHA is all marketing and a distraction.

It wants to tackle poor air and water quality but the EPA just got defunded.

It wants to promote healthy eating, but the admin gutted SNAP benefits that would do just that.

Biggest killer of kids? Guns. Totally silent on that.

This was painful to write. I hate that Emory’s new interim president, on her second day of office, just last week, called for abolishing DEI programs at Emory.

The President of the United States is threatening to go to war with an American city.

This is not a joke. This is not normal.

Donald Trump isn't a strongman, he's a scared man. Illinois won’t be intimidated by a wannabe dictator.

This is the digital stasi. Social media influencers utilizing tips from followers for content that they monetize while working with state actors to target the people they want.

It's all a spectacle packaged as content. Destroying people's lives for profitable ideological bloodsport.

Refusing to "trust the experts" is meant to be a brave, responsible position.

But (as Carl explains in the thread) there is too much knowledge in the world. You have to trust *somebody*, much of the time.

If you have no trust in experts, you end up trusting the idiots.

Phang: The Constitution says representatives shall be determined by adding to the whole number of free persons.

It doesn’t say you’re only supposed to count U.S. citizens.

Trump says you’ve got to redo the census but can’t include β€œillegals”? Tough shitβ€”the Constitution says otherwise.

Trying to understand what happened is fair/warranted/essential and I hope democratic leaders are acting on those insights. Responsible discourse is something we can all contribute to. I respect your voice, we should all have one, but I disagree 'Harris promising more of the same' is the lesson here.

No, I missed the 70% qualifier. I would also stand by having a stable democracy as β€˜good’, which I think was the case before January of this year.

Aren’t they telling us everything is great (and healthy) now? I appreciate the sentiment but far too simplistic, if not grossly so in particular to say Harris promised more of the same. Inflation WAS going down …. It’s not a democrat pres. campaign that is the reason for the free fall into fascism
