I think it's more of an internet meme that was over time taken way out of proportion.
A lot of the trans people I met online are interested in tech in some way or other but it's a biased sample because I'm also (kinda) into tech and tend to hang out in such spaces.
So I imagine that's how it came to be.
Comments like this give me the feeling that it's the neurotypicals that actually have something wrong with them and they just convinced ND people that they're the normal ones.
