Why is it Valve's job to police game content? That's a shitty precedent for any platform.
If you don't like it, don't buy it. Whether it's ultraviolent stuff like Postal or Hatred, ww2 games where you can play as literal Nazis, or the opposite side of the spectrum where you have LGBT centric content.
Bear with me, that previous sentence isn't intended to equate those two things, but the reality is a lot of people find LGBT content objectionable. By putting the publish/not publish decision up to platform owners, you're setting up a system that getting your game published is according to the political whims of whoever is in charge of that process. Any system you make here can easily be abused.
If you think banned books are dumb the same should apply to games. I for one appreciate knowing that freedom of expression is alive and well on Steam, and if I don't want to engage with content I find objectionable, I simply don't. Why is that such a foreign concept?
I would generally describe a 17 year old as a young adult. Not defending Gaetz, who is a colossal turd, but I think it's disingenuous to call a 17 year old a "child".
Edit for posterity: Yeah, Gaetz sucks, no I am not trying to say it's okay for a grown man to have any kind of sexual relationship with a 17 year old. I'm just saying that using the same term to describe a 5 year old as someone literally months away from being able to vote is just... I dunno. Imprecise. For a community called "Fediverse vs. Disinformation" calling Gaetz a pedo for having sex with a 17 year old doesn't feel correct to me.
