Back in 2016 he wrote an article in The Cut titled "What's Missing From the Conversation About Transgender Kids."[1] (which, incidentally, has since been silently corrected by The Cut's editors). It draws some pretty major conclusions from a single study [2] where he seems to overlook some pretty glaring issues that contradict his conclusion. [3]
Signal, to his credit, admits the error, although he goes on to argue it actually strengthens his argument (It does not IMO).
The criticisms of Singal's piece are pretty weak, and often resort to refuting things he never actually wrote. He explicitly notes that data is sparse - this is one of the most controversial research subjects - but it does indeed suggest a desistance rate of 50-60% absent medical intervention. Contrast that with the common claim that desistance in gender dysphoric children is a myth which is just totally contradicted by the available evidence.
Andrea James the obsessive stalker and harrasser, Julia Serrano the abusive misogynist who thinks lesbians should be shamed for not wanting dick, Ana Valens the creep who openly fantasizes about raping women in breeding farms.
If these horrible males are angry at Singal then I can only assume he's doing something right.
I’m a casual, occasional listener to his podcast (Blocked and Reported) but don’t really know his origin story and am curious to learn more.
