Pick a random thirst-trap influencer: on almost every post on their TikTok or Insta you'd see multiple comments suggesting they are trans.
Simply, there isn't a way to tell because as there is no biological marker that is a binary, as much as some would like to believe otherwise. Sex is a bimodal distribution, and as such there are people, cis and trans, that don't look like the gender you'd imagine them to be.

That's a single human body that produced both forms of gamete.
So, which is this individual, who produces both forms of gametes?
Am I, with no gametes, a null?
How would you possibly know the false negatives (the ones you “missed”)?
Once my hormones kicked in I was able to blend in so well that some of my friends didn’t believe me when I said I was trans.
And I got that confirmed from a third party who is honest beyond a fault.
And there’s a world of difference between crisscrossing and being transgendered.
