I'll not go dream on a place where everyone is "peaceful" because there's no such place and never will.
I don't expect everyone to be peaceful just most people. If most people aren't peaceful then we're all fucked no matter what ideology we cling to.
And aren't we? By day, specially since 9/11, you see Fascism moving from the Government sphere to the mentality sphere. People is getting fascist by the day, afraid of everything and up to give away their freedom out of fear of poltergeist attacks. Ghosts implanted on the mind of people preventing them from living!
We'd never been further of your dream society.
