None of those posts say anything about compulsoray expulsion, lass
Really? They are all essentially focussing on the interpretation that trans boys will , eventually, be excluded.
I don't see those guidelines saying anything of the kind or the other interpretations being put on them here.
Is there any case of a guide leader pursuing a policy of not taking the starting point that gender non conforming girls are welcome to stay on in their units for as long as they want, or until the natural end of that section?
