I know it's generally frowned upon to comment on voting, but can someone explain why the downvotes? I'm really trying to understand what in the above warranted to be voted down. I've noticed that there has been much more downvoting recently. The weird thing is that often posts a few levels down, in both sides of a discussion would get downvoted even though they seemed to make perfectly fine arguments (that I might have agreed or disagreed with). It almost feels like there is some bots that randomly apply votes in discussions.
