As to the question of "how", one way is by making the same asservations of George Washington, for one. The evidence for this is oblique, but it is enough to get one's attention. What is the true story there? I myself wonder.
You might remember all the hullabaloo over Thomas Jefferson’s liasion with a slave and how it was made into a TV movie.
Is there any chance that this aspect of Martin Luther King’s life will ever be memorialized by the entertainment industry?
It would be a cold day in you know where for George Clooney and such to get behind such a project.
