To support the idea that it is class based, I suspect we will find it is being selectively applied to poorer communities, which specifically drives the most able-to-change-jobs (often the best) librarians to move to other communities where this is not being applied.

I base my assumption on historic selective enforcement of other laws with similar vulnerability to abuse - such as selective enforcement during prohibition.

I believe that librarians, of any kind, are being targeted, be because libraries are historically a source of improved equity.

So my assertion is that any action taken against any library should be examined carefully under a lens of suspected class warfare.
