Well he said it, and it was crude, but is it really untrue?
“St. Pattys day weekend is like Christmas for black dudes who like white chicks. Happy holidays boys.”
In my opinion and I am not a lawyer, he’s trying to incite a hate crime.
Let me suggest a reason for such casting--the only reason that seems to fit the facts;--that the producer wants to create an illusion that the founding of America was not the achievement of particular people--as of course it was--but of some sort of vague ideological fantasy. The only reason anyone would think that a justifiable, much less clever approach, is if one wants to break down the concept of the continuity of a people.
Would it make any sense, for example, if someone making a play or a movie about the late great agricultural scientist, George Washington Carver, to cast the lead role with a White actor? Or how about a movie of a great boxer of any race, with an actor racially quite different, looking not at all like the achiever being portrayed?
Particular individuals achieve in life's quests. Achievement is never a matter of fanciful flights, to prove fantasy points. Individuals achieve; sometimes in groups, acting together, sometimes individually acting alone. But fudging the identity of who actually achieved at any point of time, in any particular area of endeavor, is not conducive to treating the actual achievers with respect.
