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.
As a person who has been shit posting for at least a decade at this point, 99% of shit posting is either just saying something stupid on purpose or being a cunt to someone.
"Shitposting is an art" is some shit a dweeb says online to make themselves look interesting because "I like to say dumb shit for attention" sounds a lot worse.
Like sure, sometimes it's funny to be a cunt to someone online (within reason) but let's not pretend it's something profound.
Furthermore, the fact that it's not something profound but just dumbass behavior done for laughs is the reason it can be misunderstood by honest dumbasses.
I mean if it's for a meal I get you but being mad about different type of milk for coffee is crazy
