...some of us have learned - or have attained the will - to say no to authority.
Well, think about the hippies, punks and metalheads. They are known for disrespecting authorities (funny sidenote: why is music always a part of rebellion?)
And what did they get? A whole lot of hate. Sure, they changed alot of things, but it took many years and hard fights to get the opinions through. This proves that even if we KNOW the Milgram effect, most of us are too lazy to do anything about it.
Other rebelling groups have not been as lucky, like people protesting against dictatorship in the middle east, but that's a whole other story...
You should be well prepared to write your essay or whatever now :P
