The guidance states that parents of trans students may authorise teachers to refer to their child by their chosen name, but that teachers would not be obligated to use their correct pronouns.

They just directly admit that this has nothing to do with parent choice. Even if parents want to chose, it's a firm "no, we will not abide." Parents only have the "choice" to comply with the authoritarian rules. Conform with what a bunch of straight white Christian men in Jacksonville want for you or bust.
