Kaepernick was born to a destitute black mother in Milwaukee, who put him up for adoption. His father was a deadbeat from the neighborhood. In other words, he was born into the typical black environment, but unlike most black children, he was saved by a nice white couple who adopted him and raised him as their son. This got him into good schools, sports and a middle-class lifestyle. Later, nice white coaches helped him with his sports career, first at college and then in the NFL. Jim Harbaugh made Kaepernick a legitimate NFL player.
Kaepernick has decided to respond to this amazing run of good fortune, almost exclusively the result of generous white Americans, by giving his middle finger to his fellow Americans.
