Rather than "stifling" moderation, IMHO H.SE does a poor job of aiding new users ask questions. It appears that the interface offers little (relevant or up to date) guidance for asking questions that meets the expectations and requirements of the community today.
The advice immediately visible to a user asking questions. Not particularly helpful.
The best available documentation is hidden away behind a link unintuitively named "asking help", and in my opinion fails to make it clear that the community has a poor tolerance for list-type questions or questions answered by wikipedia.
I believe that this ambiguity, and the resulting conflict of expectations, significantly contributes to the frustration experienced by new users. I suggest that our asking help page should be updated to better, more clearly reflect the community's rules today.
Moreover, I believe our How to Ask infobox should be rewritten to provide clear guidelines of what to avoid (i.e. opinion based, list type, or wikipedia answers).
Having said that, the rest of this post makes very little sense. The study of history is not at all "inherently connected to morality", a bizarre claim that has no apparent relation to the linked question. AFAIK, that question was closed due to being overly broad, rather than some sort of philosophical differences with the community that the OP seems to believe they are experiencing.
