Being "big" means a whole lot of nothing when put into a fight situation. Some of the worst fights I've witnessed were with "big" guys who thought they were somehow superior because of their size, didn't work out so well for them. Being strong can help, but it really only takes 1 good shot and down someone goes.
Don't get me wrong, I'm not defending any actions that he is alleged to have done. I would have no problems saying something to his face and I'm 5'9 195 as I've said it to peoples faces in the past for doing things along these lines. I'm not a "Timmy tough nuts" guy, but I am a firm believer in standing up for those who cannot stand up for themselves. Technology is an amazing thing, it makes people experts in all fields and gives them a sense of bravery that would never be acted out in a real life situation. I get your point, and I'm not arguing against it at all, just funny to see so many keyboard warriors (not saying you're one, please don't take it that way) nowadays.
