The study you linked to is dubious. First off, it focuses on India and India's culture is far different than the culture in the West. And the explosion of people identifying as trans is mostly a Western phenomenom.I could provide more but my claim is clearly not speculation.
Second, it doesn't mention comorbidities, and in the trans population comorbidities are common, so your study appears to be making a causation / correlation error.
Third, it conflates suicidal thoughts to suicides, and of course those are two very, very different things.
I understand that trans people face a lot of challenges, and we should provide the best help that we can. But that requires being honest about the true nature of their various physical and mental health conditions. For example, it's frowned upon to say that gender dysphoria (GD), is a mental health condition (for fear of stigmatizing?), but it clearly is, given that talk therapy is almost universally seen as a key component of care for people with GD.
