Yeah, but it's their choice.

It's everyone else's choice to be puzzled by how they're going about it, and their motivations, and to write about that puzzlement, if they like.

Here the librarians are not defending free speech but take a political position on this issue.

For example, they could have put up a book "Book about White Lives - The European Experience".

This wouldn't go over well in the current political climate, I assume.

So since the police officers are on the other side of this issue, it makes sense that they wouldn't want to be implicitly defending the opposite side.

...but they changed it. Also, they're not actually on the other side of the issue. Not really. That kind of us-vs-them mentality is what got us here in the first place.
