When we are in a truly free and open system. Why does a down vote even matter? That is the question I've been asking myself. If 20 people like something it will say 20 votes. If 100 people like something it will say 100. A down vote skews that so you no longer actually know how many people actually like it.
There are a lot of things I don't like. I'm not particularly fond of Communism or Socialism. Yet I have no intentions of telling them they should not be able to talk about it. In fact knowing how many people DO like a topic is really the important statistic.
If we were voting for a leader, or a position perhaps then it does matter as there can be only one. Yet as far as I know in the steemit environment we are not in a "there can only be X" type of situation.
