Dude, there's no violent incitement here. Let it go.
I get that this sort of content makes DART unappetizing to outsiders, but even in its heyday where more moderate discussion prevailed this site was never bringing in a steady influx of genuine newcomers (re: who had no prior connection to debate.org). All this space, and its proposed successor, really has going for it is the long-timers who've been autistically rehashing the same arguments for 10 years, and then once in a full moon someone like Best Korea who's just as unhinged as they (we) are. If you drive off those people through overmoderation, what will remain?
We can't realistically compete with Internet 3.0, like Reddit or whatnot. The one and only thing we can do is play to the strengths of Internet 2.0. And by strength, I mean the fact that Internet 2.0 was a golden age of free speech and free expression, something that promised to push the boundaries of man and his civil liberties; the product of a gentler age where the Western Left still believed in these values. In contrast, Internet 3.0 is an illiberal cesspit of heavyhanded censorship. It seems like every Reddit page, no matter the topic, has the same copy-pasted rules against "hate speech" and "bigotry" (narrowly defined as the right tribe criticizing those demographics favored by the left tribe and never the other way around, but I digress).
That DART is a surviving bastion of Internet 2.0, that it stubbornly flies the old flag of the enlightenment long after popular sentiment has turned against enlightenment values, is something to take pride in, not be ashamed of. That's not to say we ought to be proud of the ravings of users like the OP, but we should be proud that the right of users like the OP to say their piece is respected here. This was something we all took for granted until the minute you signed on as moderator. But you are still very early into your tenure, and still have ample time to leave a good legacy instead of a bad one.
Seriously, just let it go.
