Many of us on STEEM are sensible Libertarians or Anarcho-Capitalists. We may have our differences. But we share many common grounds. Free markets and Non-Aggression Principle are two of those. When these values get attacked, being educated enough to defend them eloquently is a great thing. Understanding something and being able to debate on the topic are two different skills (Do you imagine Einstein or Tesla to be the greatest physics teachers of all time? I don't think so) I do believe that knowing the right way to debate something wrong can keep other ideologies from infecting the public discussions.
We need to provide good points and counterpoints to the masses to make sure that they get the best information to make the right decisions. You job is not to brainwash anyone or drag them into enlightenment. Your job is to deliver them to the knowledge and wisdom whenever you can.
