If you haven't seen the speech yet, watch it. And read it. Really, I think you should both watch it AND read it. It is easily the best speech by a public figure I have ever heard in my lifetime. I'm pretty sure I could still say that if I was twenty years older. I don't know, whatever, this speech has completely transcended anything that I have ever witnessed in American politics.
I'm not even going to link to it. Seriously, it's the fucking internet, it's not that hard. Google "best speech ever, period."
Oh, and one more thing, prompted not by the speech itself but by all this white-person rage over Jeremiah Wright's comments: If I ever hear another white person complain about 'reverse racism,' I am going to punch them in the face. Seriously. Get the fuck over yourselves. "Black people blaming stuff on white people is racist." Really? Do you even fucking KNOW what racism is? No, you fucking don't. Racism as a concept (oooh, it seems like the opposite, but really it's the same thing!) and racism as something that you fucking experience as a limiting and oppressive force throughout your entire life are two totally different things. So shut. The fuck. Up.
