How is there any way to know the demographics of TQ+ identified children in any way that supports and betters education and provision for those children without knowing clearly all the relevant information, the basic first of which is sex?
For a start, we know already that we are talking in massive majority about teenaged girls. But which teenaged girls. What's the crossover with other needs since there's a lot of floating suggestive information that many of those girls are likely to have Autism, diagnosed or undiagnosed (and unsupported), mental health needs also both diagnosed and undiagnosed (and unsupported), trauma, history of CSA/DV/DA, is this equal across all areas and socioeconomic backgrounds, etc etc etc
If we don't know then the data does nothing to help improve the circumstances and chances of those children and gathering it is just about some adults patting themselves on the back about how very very open minded and lovely they are. And no. If you're not focused on how does this data improve things for those kids, it does not signal to others how very lovely and progressive you are.
