Do the racists that supports George Zimmerman through donations know that he's bi-racial?

Zimmerman was born on October 5, 1983, in Manassas, Virginia, and is the son of Gladys Cristina (née Mesa) Zimmerman and Robert Zimmerman, Sr.[2][3] Zimmerman is the third of four children and his siblings include a brother, Robert Jr., and two sisters, Grace and Dawn.[4][5] Gladys Zimmerman was born in Peru and has some black ancestry, through her Afro-Peruvian maternal grandfather.[4] Robert Zimmerman Sr. is an American of German descent and served 22 years in the military working for the Department of Defense for the last 10 years of his military career. Before retiring to Florida in 2002, Zimmerman Sr. had served as a magistrate in Fairfax County's 19th Judicial District.[4][6][7][8] George Zimmerman had identified himself as Hispanic on voter registration forms.

It was a Black on Black crime. Makes perfect sense now. It takes about 500 years for the black germ to be removed from a person's ancestry. Sorry if this has been posted before.
