The 2015 US Transgender Survey cited in your link was commissioned by the National Center for Transgender Equality (an organization that was founded by a transgender activist).

The study was performed online and links were posted exclusively in transgender support forums.

Your standards for "evidence" reach the heights of biased activist SurveyMonkey CSVs? I'm convinced!

the study was intending to measure the rate of suicidal thoughts among transgender people.

Seems like a great way to get a lot of datapoints is to use a transgender forum. Seems like a great way to measure suicidal thoughts is to ask "do you have suicidal thoughts"

So seems like a great approach to gather a lot of evidence for the question at hand?

Seems like you just don't like the evidence because it doesn't reach the rather bigoted conclusion you want it to
