If I remember correctly, sometime on this thread it was suggested that ‘all’ children have the right to privacy in a change room.
This can be taken two ways. First, of course, if a child wishes to use a cubicle, they should if one is available.
However, schools don’t have the space or the time to allow every student to change in an individual cubicle. My child’s recent build primary school had their senior class changing in make shift rooms, not even purpose built change rooms.
There are also no rights governing policy for organisations in general to provide privacy from the same sex category of people in that way. Hence there are still communal changing rooms for each sex.
It is an unreasonable expectation that policy is changed purely to suit male people who have identities that have then rejecting male single sex provisions. As they are not female people, they should not and should never have been accessing female single sex provisions.
In school, it is unreasonable to say that the solution is to have individual cubicles because all children have a right to privacy, when that ‘right to privacy’ is being misrepresented.
