Took this from +Upworthy. I don’t know a lot about Mr. Sheen, but I do know this speech hits straight to any advocates heart.

Each time a man stands up for an ideal, or acts to improve the lot of others, or strikes out against injustice, he sends forth a tiny ripple of hope, and crossing each other from a million different centers of energy and daring those ripples build a current which can sweep down the mightiest walls of oppression and resistance. ~ Robert F. Kennedy
