One would hope racism is a thing of the past. It hasn't been totally wiped out, but something even more dangerous has taken its place. It's 'false racism', or calumny.
Racism is a horrid a sin. But false accusations of racism at someone who is not racist at all, is typical of one who uses calumny, or injuring another person's good name by lying.
Why has this been so prevalent? The accusation still seems to work. Everyone has been so paranoid about being racist, even a false accusation tends to taint the person accused.
Cases in point, where calumny has raised its ugly head recently:
A) Obama's friend, the scholar Henry Louis Gates, was arrested by a white Cambridge police officer (Sgt. James Crowley), and President Obama immediately drew the most sinister interpretation of any police officer's motive [profiling], and did not let the facts speak for themselves. Obama quickly sidestepped, and promptly requested Crowley join him at the White House for the much ballyhooed 'beer summit'.
