The part on trans males doesn't make that much sense. They may have male brain chemistry but I'm recalling research on finger digit ratios in transsexuals that seemed to point to transsexualism being caused by low prenatal testosterone levels across the board (2D/4D ratios were higher in transgender participants regardless of birth sex). Other studies suggest little correlation, so in the end, it's still quite hard to say.
Aside from that, I think it's a bit misguided to come to such conclusions based on anecdotal evidence, which is probably even less reliable owing to the general tendency where outliers of all sorts will be shared more as evidence. You don't tend to notice... (read more)
