I don't like the "both sides are the same" tone in this response. Imagine someone who makes an explicitly-racist-game-for-the-sake-of-being-racist. What kind of game would they "hate and not want to exist"? Probably like a game with feminist messaging or something. The implication is that somehow these two games are equal in speech value and counterbalance each other?
It's basically saying: "There's awful shit here, but now YOU are allowed to say awful shit too!" I don't want to say awful shit.
There's a difference between allowing a full range of opinions, and allowing garbage. This is a storefront. Nobody would bat an eye if Valve set a moderation policy with clear guidelines. It's normal for a store. Instead they just say, "screw it, literally anything not illegal is allowed." To be clear, I'm fine with a fairly loose policy and with controversial games, but please have SOME policy to weed out the useless bits.
Now when a developer makes an honest game, they can watch it briefly blip by the "new releases" page as "Kill the Jews Simulator DLC #13934" floods the rest of the page. It's just another burden for honest developers who have to deal with their games getting diluted by shovelware; now it's diluted by horrifying shovelware.
