The discussion will likely bring to light facts that some in the discussion didn't know. Even with no immediate change accomplished, people get a feeling for another, a chance to formulate opinions that may have been tenuous before, and the past informs the future.
As to whether my actions were pointless, there decidedly were not. I enjoyed putting my opinions down, and thinking about the matter, so in that manner it entertained me for a while. An upvote received leads me to believe someone found some merit in what I said, whether it be a reinforcement of their existing views, a fresh look at something they hadn't thought much about, or some other reason. Your thoughts on how pointless it was for me are, to put it bluntly, irrelevant. To some degree, so are my own thoughts. We don't control how important something is, we simply strive to steer it to our desired level of influence. How much control do you truly have over whether you remember this exchange a year from now?
