Unless you abort everyone who is rational or honest, I don't think you'll notice much of a difference.
Game developers are 'sneaky' because a large part of their job is being "used cars salesmen" trying to move their products (honesty is often a firable offense, especially in marketing), but Roguey is right they aren't sneaky about their politics and when it comes to pronoun or gender identity stuff it's less about being sneaky and more about them proceeding as if they've already won the argument.
I don't care about politics, I care about low quality preachy writing, tone, atmosphere and overall quality in games crafted by and for girls / sheltered retards. Now without the autists poisoning the world of man with their general confusion, lack of taste and inability to communicate we'll be exposed to half as many gender freaks and anime watchers. Even that would be a difference all good online citizens will notice and enjoy greatly and that's just scratching the surface.
I find the codex is actually not bad, very few posters fall for the autism traps that I leave around to identify them. If I do it anywhere else, I'll catch bags full of them with every post. But then the question is, are they autistic or just bots? Who knows, all the same to me. Get them off the internet.I swear to god I can't wait until they can detect autism in the womb and mass abortions make them go extinct.
Jesus man, you'd wipe out 80% of the Codex just like that!?
