This is pretty telling of the commission imo:

After about an hour of public comment Tuesday, the commission voted 5-1-1 in favor of the motion. Commission Chair Peggy Taylor abstained, and Commissioner Brian Rossmann, the only active librarian on the commission, cast the one opposing vote.

Some library commissions are just so bizarre in their composition, and it sounds like this one is no different. Sometimes the committee is made up of folks with next to no background in library work, or if they do it's woefully out of date, and they can prove more of an obstacle to library operations & organization (as here) than of much benefit.

It’s not a library if it only has one book, the Bible

The ALA is not a Marxist organization. It doesn't have a "gay agenda." Therefore a gay Marxist running it has no bearing on what the organization is about. It's like saying (and I wouldn't put it past them sadly) that they were withdrawing from all federal housing assistance programs because the head of the FHA is, for example, a Satanist into leather bondage. What the fuck does one have to do with the other?
