This is worth watching in its entirety. Even if you already agree with most of what she says in this speech, it is exhilarating to hear her say these words.
I think my favorite thing that she says is this: "Progress comes from changes in laws. In many places, including my own country, legal protections have preceded, not followed, broader recognition of rights. Laws have a teaching effect. Laws that discriminate validate other kinds of discrimination. Laws that require equal protections reinforce the moral imperative of equality. And practically speaking, it is often the case that laws must change before fears about change dissipate."
