It would clearly seem to be you who has not thought about this for five minutes. The absurdly broad extension you propose to the already absurdly broad policy would effectively chill all speech on any topics other than puppies or unicorn farts. Actually maybe just puppies... unicorn farts might after all violate EPA air quality standards.
Keep in mind, the average American commits Three Felonies a Day
The average professional in this country wakes up in the morning, goes to work, comes home, eats dinner, and then goes to sleep, unaware that he or she has likely committed several federal crimes that day. Why? The answer lies in the very nature of modern federal criminal laws, which have exploded in number but also become impossibly broad and vague.

You are wrong.
The top post on LW (discounting HoldenKarnofsky's "Thoughts on the Singularity Institute (SI)"), is Yvain's "Generalizing from One Example." This post has nothing to do with crimes except a mention of shoplifting rates in one footnote.
I seriously doubt you have actually read "Three Felonies a Day," or else you would not be citing it here-- it is better classified as propaganda rather than research.
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.
