This is a non men thing isn't it?
Same as with prisons.
Transgirls are girls and so must be with the girls. In practice this seems to be what happens, transgirls are treated as girls and put with the girls.
Transboys are boys. And yet usually (always?) they seem to STAY with the girls. The reason for this is presumably aorund safety, physical and maybe psychological. The reasons they stay with the girls boil down to matters relating to physical sex, even though we are supposed to pretend that is irrelevant.
So,
The girls get
Girl
Transgirls
Transboys
ie
Non men
Same as prisons, I belive that transmen remain with the women while transwomen also get put with the women (even if they are convicted rapists).
The reasons for the disparity are related to SEX
Men are much more violent tha women
Men are responsible for pretty much all sex offending
Women can get pregnant
Are generally smaller and weaker
etc
I don't envy the position of the schools.
Logically this child should go with the boys, that is what trans ideology would say. They ARE boys so they have no business being with girls.
Of course this is not what they say as it's obviously bonkers so we end up with "do what's best for the trans child" (and ignore completely the impact on all the other children).
