Usually: Downvoting is fair. It provides feedback about how the community views the quality of your posts. Posts about posting and karma in the middle of other threads are generally viewed as non-contributing.
Occasionally: People will downvote because they disagree with you, however the community often corrects this...people will upvote comments which they think are too low.
Always: The nature of Karma is to be inevitable, so there no point in worrying about it, even if you do.
