Are you serious, or trolling?

People can say things that upset and offend me.

So? What if you say something that offends someone else? I'm offended by this pro censorship post, maybe you should ban yourself.

It seems to me that the only option for the owners is for them to force mods to impose rules that restrict dangerous speech.

What the fuck is "dangerous speech?" You started out by talking about offensive speech. Offensive speech isn't dangerous. Unless you're so pathetic that offensive speech might cause you to commit suicide, which is really a personal problem because speech itself cannot do that. The only thing that could cause you to commit suicide in response to offensive speech is .... welll .... you.

So, the thing that is dangerous, isn't the speech, it's you. Since you're dangerous, why don't you ban yourself?
