We've got another question with a background in humanities which was closed almost immediately. Another such is discussed here. The reason in both cases was that it's too subjective, rather argumentative and no objective answer could be provided. It seems to me this might be a pattern we need to be careful about. It seems to me that both questions and discussions around them implicitly assume that the question cannot be objectively answered. That however rules out any scientific discourse based on softer criteria. I argue that such questions should not be closed so quickly, there indeed might be good answers to them rooted in research in humanities, history, sociology, etc.
Considering the discussion here, my feeling is that due to the current composition of academia.SE audience which is skewed towards people from exact scientific disciplines, we might be too dismissive about questions from humanities. This way, we won't succeed to attract people from those areas. We should rather find a way to embrace such softer questions.
