Agree. Making peace is important, and there's a big difference between making peace and agreeing. One can respectfully disagree without having to be violent about it. The reality is that the establishment is usually right; that's why they are the establishment. That doesn't mean that they are always right, by any means, and authority should always be questioned, but should also be given the benefit of the doubt, assuming a position that they hold is held by the majority of all people. Most people are reasonable. So I'd say that one should make peace with the establishment, but still respectfully and strongly disagree if one is so inclined. But peace is the key word; violent, radical change is unlikely to win approval from enough people to get adopted, and smaller, more mainstream steps first in order to test the potentially unknown effects of the change before moving on to more radical change is what mature, responsible, prudent, pragmatic people do.
More-or-less my line of thinking (though I think the question is loaded and could mean other things).
Great post, BTW
