You know, there is always a third option between agree and disagree. You can agree, you can disagree, or you can accept that what you believe is more nuanced and parallel to either choice. The fact of the matter is that we need to be able to abstain from weighing in on subjects if we believe they are more complicated than they are being presented, or because we believe that we are missing a critical component of a discussion.
This is all simple, but that doesn’t mean it isn’t valuable to consider. Just because a thought is simple doesn’t mean it cant make a difference (at least in how people treat one another).
