“Sex-based rights” are contradictory nonsense
The term is a dog-whistle slogan, coined just to exclude trans people, with multiple meanings — none of which make sense.

The fucked up thing is this is *far* from the worst thing I've seen said about trans kids by so-called "gender-critcal" people. When Brianna Ghey died a lot of them set about trying portray her, a child murder victim, as a pervert.

New article in TSN in which I look at European Social Survey data which shows that “observational coding” of gender can create substantial errors in survey results.
The implication is that this practice is unreliable and should be abandoned, contrary to the Sullivan Review’s recommendations.

Pure moral panic. How, precisely, would a child who experiments with a different haircut or pronouns get “locked in” to a trans identity?
The parents who had no problem letting her identify as trans suddenly restrict her from identifying as cis? It makes no sense.

It's also just not evident based. For all the evidence Cass had tried to amass, this speculation that kids who might have ceased being trans are being frozen in time rather than helped to develop their growing minds, identity and agency by exploring and expressing it actively has zero evidence.
