Funny that a "plus/minus" changes how you see the post. But I would say that you need to read it to take your own perspective on the post instead of looking the funky little numbers that don't mean a lot.
Ps.: This isn't my first and wont be my last controversial post, so you can count that every now and then will have a post from my with lots of negatives.
Edit: Funny that from what I can see it's a 40%/60% ratio. Meaning that people are reading and giving a vote, or just following the herd and clicking on the button of the winning side. I wish I could have the time for each vote to make a more in depth view of it.
