I doubt you are gender critical or ever have been. If you were, you wouldn't be saying this.
It is quite obvious to any fool that once women's safeguards are relaxed enough to include men, then women have no sex based protections anymore.
And if self ID is on the table, we will see more of this playing out in schools, a place where children should be protected and nurtured, not a place where girls are taught to drop their boundaries and accept that boys are girls if they say so.
With sexual violence soaring in schools, why would anyone want to make that easier? Unless they have an anti safeguarding agenda. Which includes positively affirming young children to transition and destroy their bodies and potentially their mental health.
