I just don't understand how a person can criticize something they haven't seen (or read) based upon snippets (or, their own preconceptions). That just baffles me! I think the issue boils down to a lack of critical thinking ability and this need to flatten out what is/is not "authentic". I am certainly not saying that everyone has to like everything, but I do believe that its difficult to raise opposition to something when you don't know what you are opposing. Apparently the blogger (that I referenced) is upset with Marable for his allegations that Betty Shabaz and Malcolm may have been unfaithful during their marriage (based upon his research). So what? Last time that I checked, both of these individuals were human with respective human shortcomings (that plague all of us), so it is conceivable that infidelity could have played a role in their marriage. More importantly (from the perspective of Malcolm's legacy), that's a family issue and it does not diminish from the interesting dynamic presented by his life story.
I felt the same way about the "organizer" that I traded emails with about The Scottsboro Boys. Beyond that fact that the cast is 99.9% black (which isn't necessarily a barometer for anything), the telling of this story and the manner in which it was done (as a minstrel) served as a harsh reminder of how far blacks have come (and, thanks in large part to certain entertainers who shall remain nameless for now), how far we have to go to have our humanity universality recognized.
I can just hope that we (all of us) will continue to evolve in our thinking (naturally, myself included), some of the things that I read and see are just...well, crazy.
