1. You don't know what his biases are.
2. Everyone is biased.
3. Moderation is a service done to you for free. You can complain but they're still cleaning up your messes. Truly a thankless job.
4. You did say IMHO so....
I was a moderator on 2 or 3 boards. It's shitty and the departure of productive posters from here is an example.
I like how points 1 and 2 relate to your perspective on point 3. I know your bias because you're demonstrating it there. Just like I know CA's biases because he demonstrates them. He's biased against reasoned discourse, evidenced by embracing wild-ass conspiracy nonsense. Since he can't recognize intelligent debate, because he's so entrenched in conspiracy nonsense, and since he's a self-professed anarchist, he values the trolls, seeing them as gadflies who stimulate discussion.
Now you tell me how this is a good recipe for moderation? MLW is what it is because HE made it that way. It's a clear reflection of his tastes.
