I would support any research into this after multiple suicide attempts by my transgender nephew.
Its not research you're supporting though. A lot of these charities aren't big on research.
Serious question though, and I'm asking this genuinely. Don't you think that your nephew deserves to be served by charities that take safeguarding seriously?
Don't you think that if these charities are purportedly acting in your nephews interests, they should be able to stand by their own medical expertise?
Have you read the interim Cass report? Do you think that charities for TG children should be familiar with the contents?
