Most commentators there are playing to the gallery rather than answering the questions. The size of the question subs actually makes it harder to get a good answer.
The best karma return per comment is not to craft a lengthy, thoughtful reply but to fire of a snappy one liner as fast as possible.
What I have written is also not inciteful or original. It has been well know for a long time and is pretty much a factor of sub size and the demographic spread of the user base (which skews young, cis, male and american).
