Well one obvious reason is that they're more likely than cis people to be able to contrast actual lived experiences.
Also, is it "always"? Or are you just identifying it here?
>contrast actual lived experiences
what do you mean by this, as it relates to the comment you replied to?
People who have lived presenting as both male and female may be able to speak on contrasting experiences that cisgender people can only approach via projection.
If you dont agree please live as a woman for a year and get back to me ;p
It's a coherent statement, I just don't understand how that might explain the conjecture that trans women far outnumber cis women on HN.
