Race-blindness was never the left-wing position, unless your definition of left wing is maybe the feel-good commentary of prominent elected moderate Democrats, who had to appeal to the majority rural white populists. I don't think many or any prominent minority civil rights leaders led on any sort of color blindness platform.

In fact, the 70's and 80's were all about embracing blackness.

If i were prickly, i'd be making insinuations about you personally.
