I expected peaceful demonstrations and was shocked by the violence on Toronto Streets. It is sad to see so much energy spent on destruction. Here are some quotes that reflect best my thoughts on this matter.
"La violence, sous quelque forme qu'elle se manifeste, est un échec." Jean-Paul Sartre
Violence, no matter in what form it shows itself, is a failure.
"An eye for eye only ends up making the whole world blind.” Mahatma Gandhi
“When liberty comes with hands dabbled in blood it is hard to shake hands with her.” Oscar Wilde
"Non-violence leads to the highest ethics, which is the goal of all evolution. Until we stop harming all other living beings, we are still savages." Thomas A. Edison
"At the center of non-violence stands the principle of love." Martin Luther King, Jr.
