This one comes from LJ user stickykeys633 in the blackfolk community:

Dear lovely white people in real life,

The people who can rightfully declare racism to be over? Are the people to which the racism is happening.

Don’t worry, we’ll let you know.

Yes, yes, and yes. I don’t know many times a day I feel the need to say this. Just because we no longer have White and Colored signs on the fountain doesn’t mean it’s all over. As white people, you don’t ever experience it. So why do you feel you have the authority to say it’s over?
