There are possibilities for civil disobedience. Imagine if every teacher in a school were to address a trans student by their proper name. Imagine if every teacher in an entire school district were to do so. What are they going to do, fire them all? Think of the logistics of trying to hire hundreds of new teachers at a moment's notice.
I know this is not practical. For one thing, too many teachers would be on board with this legislation. But civil disobedience needs to be at the front of people's thoughts these days, especially audacious civil disobedience.
