You're welcome. Not a whole lot of people, even here, know these sorts of 'minor' details about these two. Or, for that matter, that the Black Panthers were a *revolutionary communist* organization. They just think of them as being racists. In fact, Reverend Wright's Black Liberation Theology (President-Elect Obama spent more than 20 years in his 'church') is a revolutionary-communist political ideology which Bill Ayers and the Weather Underground also advocated, along with their close allies, the Black Liberation Army. These two groups, working together, launced many bombing attacks and killed several police officers over a 2 decade period.
