I've been conducting 2-hr workshops designed to introduce Everyday Antiracism to educators. Here's the most recent version of the powerpoint slides I use.

As you'll see, a "gallop through history" is one key aspect of the workshop. In that "gallop," I discuss the history of race categories, racial inequality, and racist ideas about "types of people," in order to build the warrant for why "antiracism" is necessary in 2008 at all. I may well post a digital version of that "gallop" here soon.
