When you break walls
   Caveat:  This doesn't directly apply to the school "guidance" because this wasn't a 
legally required confusion, but it still shows what can happen when you break borders and normalize confusion.
When I served on a jury in 2014, 
the case in question was a rich Saudi dickhead who engaged in a sort of trapping fetish with girls in a restroom.  Grab** the girl, hold her against the stall door, dryhump her.  
How did he 
get into the Ladies restroom without being instantly kicked out?  Because the restroom was in a "gay" bar where cross-dressers frequently used the Ladies room.  In other words, the dyslogic of Trans was part of the culture there.  Saudi dickhead was NOT a crossdresser; he was firmly heterosexual.  Stupid defense lawyer tried to claim he was homosexual, but it didn't work.  His dryhumpees were always female.
If the Trans rules become part of written law, a jury wouldn't be permitted to toss out the stupid arguments about confusion.  Stupid defense lawyer could invent a "gender" defined by the need to trap and dryhump women.  The jury would then have to treat the victims as discriminatory bigots for complaining about Saudi dickhead's aggression.  Humpy McHumpface*** was only expressing Humpy McHumpface's gender.

** Footnote 1: Humpy McHumpface is the 
official pronoun for the restroom-dryhump gender.  I just defined it and you can't say I'm wrong.
*** Footnote 2: The crime was an obscure term that meant sexual assault.  We had trouble with the definition because it was clear from various witnesses that quasi-sex was fairly common in this bar 
in the context of dancing.  The grabbing and trapping made these actions special.  The girls were not expecting to find a male in their restroom, and they weren't willing to be grabbed.  In other words, 
assault was the relevant variable.
