It's the dreamers — no matter how humble or poor or seemingly powerless — that are able to change the course of human events. We saw it in South Africa, where citizens stood up to the scourge of apartheid. We saw it in Europe, where Poles marched in Solidarity to help bring down the Iron Curtain. In Argentina, where mothers of the disappeared spoke out against the Dirty War. It's the story of my country, where citizens worked to abolish slavery, and establish women's rights and workers' rights, and rights for gays and lesbians.
