... Which is why whenever I want to bully disadvantaged groups I make sure they cannot speak.

(That is to say, "Don't be daft!")
That's censorship, not discrimination. Different problem needs a different solution. Once the information's made available, and complaints are possible, only then can antidiscrimination measures be implemented with any chance of success.
Have you ever known anyone to go out of their way to deny a dead person the opportunity to speak? If someone sat up near the conclusion of their own funeral and disputed the previous speaker's main points, I doubt they'd be shouted down.
What do you believe that most people on this site don't?
I'm especially looking for things that you wouldn't even mention if someone wasn't explicitly asking for them. Stuff you're not even comfortable writing under your own name. Making a one-shot account here is very easy, go ahead and do that if you don't want to tarnish your image.
I think a big problem with a "community" dedicated to being less wrong is that it will make people more concerned about APPEARING less wrong. The biggest part of my intellectual journey so far has been the acquisition of new and startling knowledge, and that knowledge doesn't seem likely to turn up here in the conditions that currently exist.
So please, tell me the crazy things you're otherwise afraid to say. I want to know them, because they might be true.
