I live in NY and am here to say that I have actually googled that question.

"So, despite being married to a Black woman and the father of a biracial child, Bill de Blasio is not Black? And is, in fact, still White?

I couldn't even get through it. The level of Step and Fetchit coonery was just too damn much.

Bill has two biracial kids. A daughter and a son. Not as a "gotcha", just as clarification.
