The motivation isn't there because you are too afraid to show your face or tell anyone who you are. I'm not afraid, in fact I've met quite a few people from usenet IRL, even people that I was quite adversarial with for many years.
Well, ever since practicing Hirsadut (intensive Israeli Martial Arts) for years, I've not backed down from anyone in a physical confrontation. So the scenario would more likely be that I would run circles around your fat ass.
