It seems to me these days more than ever we are divided in every possible was. Referring to people as 'sheeple' is just another way to divide us. Even music and art, which in the 60's was uniting people to create change and challenge the status quo, is as divisive as race, class, and nationality.
Yes, smart people argue a lot, but so do ignorant people who argue about issues highlighted in the media by those institutions that profit from the way things currently are and fear the power of organized people. Keeping us fighting about things of no real consequence has been a very effective distraction historically and as obvious as their tactics seem to many, there are still those who seem oblivious. Sheeple, if you will. They shouldn't be discounted though and are needed to create a new future.
Fair enough, I've never thought that woodstock etc has also created division all that, makes sense. Once I was chatting with a gay friend about lgbt stuff getting more mainstream acceptance, and he was like "Dude, I couldn't care less about that, that's not the real issue people are facing".
