Yikes. This post strikes me as harmful and irresponsible. Less Wrong is less of a community than I'd like -- less there for its members, less mindful of what effects each person has on the others and on the rest of the community.

I agree, actually, that all subjects are fitting subjects for rationality. But if you’re going to talk with someone who is suicidal and unstable about the detailed pros and cons of killing themselves, you risk having seriously bad consequences. Saying “but free speech is good, and thinking through all subjects is good” just isn’t enough of an answer to that. Talking about some subjects brings responsibilities -- responsibilities for thinking carefully through who you might harm, and how you can support them during the discussion. Offering help.

LW has a number of seriously depressed people.

Since this thread is already up -- let's make an effort now to reach out to anyone who needs reaching out to, to increase the odds that depressed LW readers have social support. That is: if you know a LW-er online or in person who is depressed, make contact with them. If you're a good listener with a couple of free hours in your life, echo Alicorn's offer of help. If you have a bit of spare money and a good CBT book to recommend, offer to mail it to someone who'd read it. If you have useful well-being tips and can write, consider making a front-level post (on happiness tips or CBT or the like, not on topics that might prime suicide).
