You seem to be on the money with this, all troons I know spend the entire day playing vidya or sperging or begging for things in twitter/reddit/whatever. They dislike work more than any other collective I've witnessed on the wild, and most don't even have hobbies outside games/porn/cartoons/sperging.
But, I feel there has to be something else, people wasting all day in front of a screen is only new in relative terms, and there are people who do the same thing but don't troon out. Like, we have had like 30 years of connectivity, easily available porn and videogames, and groomers have existed since the dawn of time, so what's the missing ingredient?
One thing I did notice is that troonbians never speak of siblings unless they have sisters, and a lot don't have any siblings to begin with. If they have sisters they are only mentioned as a source of clothes, and they tend to hate their brothers if they have any. But a lot simply are the only child of their parents, at least in my unfortunately large experience with these subhumans. Come to think of it, I don't ever hear troons say anything nice of their family in general terms, if they aren't downright un-personed (or ghosted or whatever the cool kids say nowadays). It's something I haven't noticed in other internet tribes to this extent. I wonder if that's a factor.
Troonbians are also one of the few types of person that'll react to someone's close family dying with derision and making crass edgy "jokes" or downright insult you for grieving. Very feminine.
