Lol, I see you're The Capt. of USS Dou-che Canoe in thinking it is tough guy attitude. If called me a tool bag I would laugh because it words from someone insignificant hat has no moral bearing on my life or outcome. You wouldn't associate with me because you are probably to busy in your life thinking that everything is rainbows and butterfly's and I wouldn't want someone like that who is so far from reality. Guess what, regardless how you think that insignificant push was, you don't know the history of these two. Maybe that push or cold-cock in the back of the head (We weren't there) was something more between the two. You fail to grasp the idea that every action has a reaction. Everyone will have different opinions.
The guy had every opportunity to not touch Nelson, just like Nelson had every opportunity to not kick him. I bet you're the kind of person who talks crap to someone and then runs to the police for protection when you started the whole thing. Don't tug on the tail end of a snake if your not prepared to have what's coming.
You keep thinking these great thoughts while you have double rainbow playing on repeat.
