I feel like I'm out of the loop on this. Could you elaborate?

The Weather Underground was founded by students from the University of Michigan, who spent their college years arguing that people should violently resist the government. When they graduated, they didn't moderate out of these ideas; they doubled down, started an organized bombing campaign, and successfully hit targets including Capitol Hill and the Pentagon.

Insane. I didn't know about any of that, though I did think you were referring to the api and didn't know about the name's origin.

But those were the chic kind of terrorist, not like the Jan. 6 crowd.

Unlike the Jan 6 crowd, they actually killed people.
