I think your example is rather atypical to be honest at least in the wider West. Emma West being the more typical one. Very much like with hate crime laws there is controversy whether hate speech against white people even is hate speech.
What would be considered unacceptable for one group is not unacceptable for another. The star of the recent popular movie Django Unchained, Jamie Fox joked for example:
"I get free. I save my wife and I kill all the white people in the movie," Foxx said to thunderous applause. "How great is that?”
in light of his other comments this is interesting
"As a black person it's always racial. ... when I get home my other homies are like how was your day? Well, I only had to be white for at least eight hours today, [or] I only had to be white for four hours."
Foxx went on to say that “black is the new white.”
Whether this combined is ominous, righteous or innocuous depends on your model of the world. That how such laws are applied depends heavily on what kind of model of the world judges or police officers are likely to use is hardly disputable however.
Oh, I agree fully that such laws are problematic and open to abuse, and that it might well be better for no such laws to exist at all. Nonetheless they exist and should occur as a (possibly very low) cost in the calculation of the expected utility of advocating violence.
New proposed censorship policy:
Any post or comment which advocates or 'asks about' violence against sufficiently identifiable real people or groups (as opposed to aliens or hypothetical people on trolley tracks) may be deleted, along with replies that also contain the info necessary to visualize violence against real people.
Reason: Talking about such violence makes that violence more probable, and makes LW look bad; and numerous message boards across the Earth censor discussion of various subtypes of proposed criminal activity without anything bad happening to them.
More generally: Posts or comments advocating or 'asking about' violation of laws that are actually enforced against middle-class people (e.g., kidnapping, not anti-marijuana laws) may at the admins' option be censored on the grounds that it makes LW look bad and that anyone talking about a proposed crime on the Internet fails forever as a criminal (i.e., even if a proposed conspiratorial crime were in fact good, there would still be net negative expected utility from talking about it on the Internet; if it's a bad idea, promoting it conceptually by discussing it is also a bad idea; therefore and in full generality this is a low-value form of discussion).
This is not a poll, but I am asking in advance if anyone has non-obvious consequences they want to point out or policy considerations they would like to raise. In other words, the form of this discussion is not 'Do you like this?' - you probably have a different cost function from people who are held responsible for how LW looks as a whole - but rather, 'Are there any predictable consequences we didn't think of that you would like to point out, and possibly bet on with us if there's a good way to settle the bet?'
Yes, a post of this type was just recently made. I will not link to it, since this censorship policy implies that it will shortly be deleted, and reproducing the info necessary to say who was hypothetically targeted and why would be against the policy.
