I have noticed a sociological trend in Silicon Valley that equates meritocracy with "I outrank you so this discussion is a waste of time".
Your comment is maybe kinda whiny (i wants my leet downvotez), but nowhere near the level of trolling I would reserve for a downvote.
Also, you make a good point. For me, -1 means "this comment is in bad faith and should be censored", and I have noticed it being overused on my journey to l33t status.
For what it is worth, you too almost have the downvote button, and if I see too many upvotes without some gray flickering at first, I feel like I am pandering.
Anyway, keep fighting the good fight and enjoy my upvote. Also, remember this when you get the down vote button.
Absolute power, and all that. ;-)
