"...because I believe that racism only truly exists in the mind of recists" (sic)...",

Shortly after reporting to my Camp Pendleton duty station, I found an unsigned note in my clinic mailbox: "The Ku Klux Klan has just paid you a friendly visit--next time it'll be a REAL visit."  The note wasn't imaginary.

Nor was it a fantasy when my eight year-old daughter's white homeroom teacher reviled her in front of her entire class, because the teacher was incensed she'd successfully qualified for the school's "gifted" program, becoming the first student 'of color' therein--previously that school had never notified the parents of its majority black student body that there WAS a "gifted" program.

Nor did I imagine my son being dragged from his best friend's Corvette and beaten by Oakland cops, until they learned his best friend was Darrell Russell of the Oakland Raiders, whereupon he was released without charges.

I agree "racism" exists in YOUR mind.  As well as in objective reality.
