that's not to say stringent moderation doesn't make a site less welcoming, though. it's about choosing what's the lesser evil to you, i guess.

What would be gained if they didn't "go easy on racism"? Would we all start singing kumbayah and love each other, hippy-style? Or would people be just as racist even more remote corners of the internet/world, and then slightly-left-of-center-minded individuals could pretend that all the world's problems were solved and it could continue for another 100 years?
And it still does, but it's less effective, because various flavors of cretin now have online spaces where they can meet like-minded people and nurture those beliefs, and worse still, all of those spaces reward extremism as any social media site does: subtle, balanced views are not incentivized at all, and you get the most social attention for saying the most outrageous thing in the space. We all know this, like maybe you've never thought about it before, but I'd wager almost everyone on this board has had this experience over one thing or another, even benign nothing issues.
And all of that is before we even get to the subject of things like influencers peddling YouTube videos, TikToks, or whatever to amplify those beliefs for their own profit. Whether they "really believe" these things is irrelevant frankly; in either case, people who believe these things see people being paid to represent their (wrong) ideas which lends them legitimacy.
And now we just have little bespoke engines of radicalization humming away all over the internet in the little shadowy corners, whipping people up into a lather about whatever dumbass thing they googled way back about how they can't get a girlfriend or whatever, and there seem to be a lot of spree shootings now for some reason, totally disconnected I'm sure.
Like the problem with this Libertarian "as long as you're not hurting anyone" is that it leaves a wide open loophole in there about hurting yourself, and while in many cases hurting yourself doesn't lead to anyone being harmed apart from yourself, as I keep saying: No one is an island, if you harm yourself in certain ways, you are absolutely a risk to other people.
Considering the site has been around for over 20 years and people still call out and flame racism, I think this is an uncharitable and unfounded cynicism. I'm not sure declarative claims of 3rd order effects in a system so chaotic are capable of being accurate.
