How the hell does a school board even exist that could adopt this? This should never have passed in the first place.

Because Republicans aren’t like Democrats when it comes to strategy (that is to say, awful). This is happening at school boards across the country. It’s a concerted effort to pack these boards with Christian nationalist lunatics. And they’ve been quite successful so far, there hasn’t been much push back until recently, but by now they already have a lot of control.
