On the fence comment - don't know yet haven't typed it out lol
I wouldn't have posted it on a forum if I had lost control and attacked some one.
Would I consider you a thug? no, as I don't know you enough to judge but from what you have writen I would say you need your Thinking Skills worked on as your decision making ability in stressfull situations doesn't seem to be fantastic.
You could just of easily intimidated the chap in the car with the horn with a look, glance... body language speaks volumes in my experiance.
Not insulting you here just giving some constructive feedback in a thread I can see turning into an argument.
Any way, hope you don't make it a habbit hitting people.
