You don't seem to realize that claims like the ones in the post in question are a common sort of claim to make people vulnerable to neuroses develop further problems. Regardless whether or not the claims are at all reasonable, repeatedly referencing them this way is likely to cause further psychological harm.

However, it seems that in general, the mere fact that certain statements may cause psychological harm to some people is not considered a sufficient ground for banning or even just discouraging such statements here. For example, I am sure that many religious people would find certain views often expressed here shocking and deeply disturbing, and I have no doubt that many of them could be driven into serious psychological crises by exposure to such arguments, especially if they're stated so clearly and poignantly that they're difficult to brush off or rationalize away. Or, to take another example, it's very hard to scare me with hypotheticals, but the post "The Strangest Thing An AI Could Tell You" and the subsequent thread came pretty close; I'm sure that at least a few readers of this blog didn't sleep well if they happened to read that right before bedtime.

So, what exact sorts of potential psychological harm constitute sufficient grounds for proclaiming a topic undesirable? Is there some official policy about this that I've failed to acquaint myself with?
