"Make love not war" was great when it first came out. John & Yoko expressed yearning for an end to the status quo - the Vietnam War, the Cold War & perpetual aggression. They were change agents - voicing and behaving a meaningful protest. [watch that video - hear their song]
Steve Farber also says things like "Choose to be extreme" & "Cultivate love" - and he's talking to business people (not a crowd of old hippies). Reach him on Twitter.
Love is a great word - it appeals to us all. It's the human way. It's meaningful.
But love doesn't mean leaving things the way they are. We want to change the world because we love it - otherwise we wouldn't try to improve it. We want to make the world fit for children - the next generation - because the world is dear to us. We love it.
We are not peaceful. Of course we believe in world peace. But we cause a rumpus, protest & disrupt because we are not satisfied with the way things are - with the way people do things - with current thinking. We don't keep quiet.
At least some people are noisy - fighting against the status quo. We call them change agents.
