I'm not sure why you feel impelled to behave like quite such a prick. If you open a conversation with a stranger by insulting that person (in your case, by calling me a coward), it tends not to smooth the way to a productive exchange - unless you're an autistic Labrador puppy, you are presumably aware of this. And if you then double down on that by making several more aggressive, but profoundly pointless posts, it will achieve nothing other than to generate ill-feeling. If that is what you set out to do at the beginning, then my congratulations to you because it is mission accomplished, but if not, perhaps you could reconsider how you interact with people.
