People who do anything at all to attack others are people in problem situations. Their actions are obviously anti-social in the most fundamental sense. So your point is taken in the sense that it is desirable that people simply do not do these things. But is the best way to bring about that desirable situation to encourage the sort of awareness I am trying to express here, or is it to encourage these modern forms of the public policing its own conduct by everyone judging the actions of others? I guess what I am getting at is that you can try to conduct yourself in a manner that you feel is respectful of others without becoming judgemental of others who behave differently. We are all unique and unable to fathom another person’s uniquely subjective life experience.
Decent behavior is not dependent on a judgemental position as regards the behavior of others — and self-righteousness is particularly odious… in my self-righteous opinion :)
