Saying women can abuse is homophobic but saying all men are a threat by default ergo all trans women are a threat isn’t transphobic or highly offensive
There isn't a need to make it complicated.
If safeguarding policy is that all males and all female children must be provided with separate facilities in this situation, it doesn't matter whether or not you agree with sex separated spaces politically.
The issue is that when a male, excluded by safeguarding, says they identify as a girl/woman - what has actually changed that justifies removing that safeguarding barrier?
I understand the ideological desire - it's to respect the person's choice and sense of self, it's to provide them with the identical recognition you would give to a female person.
But the person has not changed sex. The reasons for sex segregation have not changed.
Should safeguarding for girls be put aside in order to prioritise showing respect of a male's identity?
Should safeguarding have included in it, clauses that to protect some male people's feelings loopholes will be open and everyone will rely on the good chap principle and cross their fingers that no female person will end up with a life impacting trauma as a result, that could have been avoided had standard safeguarding policy been applied?
And as we're talking as if increased, known risks and embarassment, lack of privacy etc for female people are just collateral damage to higher social progress for male people and this is somehow fair and ok....? Is it fair that all female children should lose all female only, sex based opportunities across the board so that a male child never has to encounter any boundaries to their personal choice of identity? Even though there are plenty of mixed sex opportunities available to that male child, and some of those female children will not be able to access anything at all if female only options are removed from them to benefit males?
Why is it that female children are just so unimportant compared to the male ones??
