I try to balance the vibes in the post to avoid it feeling too dark. I know there is a bit of a problem where someone might write about dark and disturbing things in an academic tone and someone might not be comfortable reading that.
Obviously, it's impossible to make people happy all of the time, and it would make it harder to get my points across, if I did that, or to broach particular subjects, but I might as well avoid doing so superfluously.
That is also part of why I like things like Ferguson's review. It gets the point across. Someone did the analysis and wrote down the results. Or top-down overviews of crime. I don't think getting too dark really adds anything to it but it might come with a greater risk of reader attrition.
I mean, obviously, someone should be free to write something dark, freedom of speech, but when it comes to getting regular people to read something, that might be an obstacle.
