Meanwhile, you take down posts of people talking about how the tournament did not offer gender neutral bathrooms or how there aren't enough female chess masters, because that's "political" and off topic, but then turn a blind eye towards people harassing women on the forum and require them to keep begging you with the flag buttons to clean up your mess.
The result of this is just that the powerful majority gets something akin to a working filter and all the marginalized people don't just get lip service to their issues: they end up being unable to even bring up their complaints, because those complaints are divisive and often themselves against some terms of service banning meta-conversation (a common enough issue that this website--Hacker News--has such an indefensible clause).
This is all just not OK: you don't get to have immunity and have control. The idea that you should be able to restrict some of what happens but somehow not be even sort of responsible for everything else that happens is the kind of position you can only hold if you are part of the powerful majority, whatever it might be (cishet white males, corporate stooges, western prudes... take your pick) :/.
So, I guess, "congratulations tzs": you are demonstrating loud and clear that you think the legal position of running a chess forum that actively distorts the world view of everyone using it is more important to defend than the rights of groups like breast feeding mothers (a group that is routinely thrown off of websites and deplatfored even as alt-right groups are empowered).
(Meanwhile, the entire premise that people should get to sort of look like a platform without really being a platform is robbing the world of actual platforms, and it is ridiculous: the existence of things that almost work like platforms for the majority of powerful people means that getting people to tolerate the pain of using fully distributed systems is by and large off the table :/. Either these large websites should offer real platforms or they should be forced to not pretend to do so, so we can actually launch and use distributed systems instead.)
