Care to describe who these bad people are?

I've been to public libraries in several states known for vastly different politics and have seen the same things: quiet, calm people, old folks, and mothers with kids.

I think OP was referring to the people that are trying to shut down libraries.

Yes. As I said, people coming for, not coming to.

To come for something is an expression meaning you're going to take it away from wherever or whomever has it.

In this case, to take libraries away from regular & good citizens who've been using these treasured 3rd spaces for decades. And the librarians who've done so much to care for these treasures.

Republicans.

It's vexing to discuss issues like these because at their nature they're quite partisan, but the calling out is simply an acknowledgement rather than a partisan response.

Exactly. It's not a both-sides kind of thing. Not anymore.

Come to library meetings in our town and you will see people screaming and being removed from the building. not an exaggeration.

problem is not the patrons, so much as the ones trying to control the content available

He means bad people came to get rid of the libraries.
