Personal experience, you can always find a fight if you are looking for one. Going around with the attitude "I'm right, your wrong and see, I'm going to prove it" is provoking undo attention and changed nothing. Another guy on you tube purposely parades on the sidewalk in front of his house with a pistol on his hip just to provoke a confrontation. Right or wrong, what are you going to do if I get in your face? Did this guy look to make a change? The only attention he gets is on you tube. He wanted his 15 minutes of fame and has it only in some quarters.
Laws are what keep a society civil. If you disagree with something there are ways to change it. Look at the left. They are a minority but are pushing the majority of the changes. Most people don't care one way or the other, hence the lack of people voting decreases each election year. Doing something just for the confrontation does little to no good. Look at the occupy movement. Here was a group of morons that created a disturbance and got their 15 minutes of fame. Drugs, rape and general mayem were talked about but mostly ignored. They changed nothing.
