Whoopi offered her "sincere apologies" Tuesday, telling Rolling Stone, "It was never my intention to appear as if I was doubling down on hurtful comments, especially after talking with and hearing people like rabbis and old and new friends weighing in."

She says she's still learning -- but confirms, "I believe that the Holocaust was about race, and I am still as sorry now as I was then that I upset, hurt and angered people.”

As we reported, Whoopi faced severe backlash after recently telling The Times Jewish people themselves are divided on whether they're actually a race or not, even quoting one Jewish friend as saying ... "Not for nothing is there no box on the census for the Jewish race. So that leads me to believe that we’re probably not a race."

Whoopi went on to double down on the notion that the Holocaust wasn't about race, from her POV, by saying ... "Remember who they were killing first. They were not killing racial; they were killing physical. They were killing people they considered to be mentally defective. And then they made this decision.”
