So you arbitrarily dismiss one factor because the evidence is "inconclusive" but accept as gospel another factor that has even less evidence. That reeks of confirmation bias! As far as the most effective treatment goes how has pretending that it doesn't exist or bullying those suffering from it worked in the past? From the fatal results those policies have been an utter disaster so trying something else certainly cannot do any worse.
I was crystal clear on the fact that I'm not dissmissing discrimination as a factor. As in, those were my exact words. I simply don't consider it to be the sole factor when even transgender people who are not recognized as transgender and who report being accepted by their environment present astronomically high rates of attempting suicide, and when no other marginalized or discriminated against group other than mental patients presents similar rates. When transgender people exposed to the best possible social circumstances present suicide attempt rates equivalent to sufferers of a severe mental disorder, that raises a red flag for me. What exactly am I "accepting as gospel"? All treatment methods concerning a subject we have little knowledge about should be approached with caution, especially regarding minors. When the most popular treatment method presents no statistical evidence of efficiency, caution should be even greater. The increasing rate of children being referred to gender clinics and the broadening standards of diagnosis do not reflect that. Apparently I'm advocating for "bullying sufferers" and "pretending that it doesn't exist" because I want more research and less politicization of a significant issue.
