Al Sharpton says Colin Kaepernick's National Anthem protest reminds him of Jackie Robinson -- because the MLB legend also said he refused to stand for "The Star-Spangled Banner."
It's true ... As Sharpton pointed out in NYC Wednesday, Robinson made his feelings clear in his 1972 autobiography, 'I Never Had It Made.'
"As I write this twenty years [after my MLB debut], I cannot stand and sing the anthem," Robinson wrote ... "I cannot salute the flag; I know that I am a black man in a white world."
Sharpton says both Robinson and Kaepernick raise a "critical point" about Francis Scott Key and the negative references to slaves in the complete version of "The Star-Spangled Banner."
Sharpton also says he will not condemn Colin's protest -- because it has not hurt anyone "but possibly his own career."
