TF2 attracts Chuds because you can pretty much say anything you want in game.
TF2 attracts trannies because they saw a funny tf2 compilation, most of the cosmetics are furry trans coal and also because muh silly reddit game.
That's not how it works. Back then you would get bullied and votekicked from a game for being a faggot. Trannies are drawn to it because they can't stand the idea of not governing the thoughts of everyone who doesn't like them.
That's how old games are. They're either played by old millenials who used to play them when they were kids or autistic terminally online zoomers who happen to be either a tranny or a chud.
