I'm not sure what you're claiming is up in the air. My first claim was about the changing cohort, so if that's what you're referring to, the statistics are clear. Here's how it breaks down in Canada:
Transgender women were dominant and stable for a long time, as I said (male to female transitioners), and then trans men and non-binary cohort have shot past those levels like a rocket over the past few years.
Some of the increases are doubtless more acceptance of trans people, but it's not clear why that would affect the genders differentially in such a dramatic fashion.
