Have some patience. Comments often receive a small flurry of reflexive downvotes right after posting. If it's a good comment it will receive upvotes eventually.

I upvoted your other comment because it was a fine opinion and didn't deserve to get pushed down. On the other hand, I downvoted the above comment because complaining about downvotes doesn't add anything of use to the discussion.

Everyone gets downvoted sometimes; it's not a big deal, just a few fake Internet points.
