There is nothing racist about blackface.
The left insists on their power to define what is "racist".
It has become so bad that the definition of "racist" means anyone opposed to the left. Consider all the calls that Donald Trump is "racist" with no evidence that he is.
To the Progressive Left, as it has become, President Donald Trump's existence is "racist" because it blocks their power.
I stand somewhat corrected. You finally posted something in addition, albeit weak, better than just the title.
