Hi @michealb, thank you for your thoughts and your position to this subject. It is of course nice to know why people upvoted our posts, to tell the truth people upvote more than downvote. It is time comsuming properly read and comment those posts that you like. But as it is we are all busy in our real life. Like me, last 4 days I have had 4 days of 12,5 hours shifts and when I returned home I had only power to eat a bit and just to sleep. Those days I can upvote but physically have no power for comments, but I know that I will make those people happy with my attention.
On other hand downvoting you may completely turn the day of someone into misery, as that person will break his head thinking what he did wrong in order to deserve it. That is why in my opinion it is more important to explain why someone decided to hurt someone rather why make someone happy. Hope it does make sense?
