Sure, it feels good to go yell in the streets, intimidating your opponents. Show your numbers. Show that your willing to fight. I say,"Why fight? Why yell?". They expect us to do this. This, in history, is normal. When you do this, you are just imitating them. They march in the streets. They attempt to intimidate all that oppose them. Fighting fire with fire...only makes it hotter.
Water. Douse it out.
You want to end war on earth? Well, a good start would be by ending it in your own mind. If you openly live a life free of conflict, in all forms, it will spread. Good things catch on. People will notice, and in response, they too will begin to morph into peaceful beings.
The quote from A.J. Muste says it all:
"There is no way to peace; peace is the way."
That's it. You see the goal? Go for it.
