Watch it or don't. She did not call him a racist; what she said was "
I do not believe you are a racist and I agree with you when you commit yourself to the importance of finding common ground."... but, I also believe—and it's personal. And I—I was actually very—it was hurtful to hear you talk about the reputations of two United States senators who built their reputations and career on segregation of race in this country."
No need to cherry pick as all Democrats do to hide the entire story. Here, from your own link:
"Harris directed a portion of her answer to Biden.
"So, on the issue of race, I couldn't agree more that this is an issue that is still not being talked about truthfully and honestly. I—there is not a Black man I know, be he a relative, a friend or a coworker who has not been the subject of some form of profiling or discrimination," Harris said during the debate. "And I will say also that—that in this campaign, we've also heard—and I'm going to now direct this to Vice President Biden. I do not believe you are a racist and I agree with you when you commit yourself to the importance of finding common ground."
Harris continued, "But, I also believe—and it's personal. And I—I was actually very—it was hurtful to hear you talk about the reputations of two United States senators who built their reputations and career on segregation of race in this country."
Her comments were addressing remarks made by Biden while speaking about his working relationship with two former segregationists, Senators James Eastland and Herman Talmadge, at a New York City fundraiser on June 18, 2019.
"I was in a caucus with James O. Eastland," Biden said during the fundraiser. "He never called me 'boy'; he always called me 'son.' "
"Well, guess what? At least there was some civility," Biden added. "We got things done. We didn't agree on much of anything. We got things done. We got it finished. But today, you look at the other side and you're the enemy. Not the opposition, the enemy. We don't talk to each other anymore."
Speaking to Biden at the debate, Harris described her experience with busing while growing up in California.
"You also worked with them to oppose busing. And you know, there was a little girl in California who was part of the second class to integrate her public schools and she was bused to school every day, and that little girl was me. So, I will tell you that on this subject, it cannot be an intellectual debate among Democrats. We have to take it seriously. We have to act swiftly," Harris added.
In response to Harris's comments made during the debate, Biden said that it was a mischaracterization and stated that he "did not praise racists."
Harris followed up to ask Biden if he thought he was wrong to oppose busing in America. "I did not oppose busing in America," Biden replied. "What I opposed is busing ordered by the Department of Education. That's what I opposed."
While serving as Delaware's senator in 1975, Biden supported an anti-busing measure that was offered by North Carolina Senator Jesse Helms, who opposed civil rights, and a year later in 1976, he introduced his own proposal to stop the Justice Department from busing to desegregate schools."
Do not get me going about Joe Biden and Robert Byrd. His self proclaimed mentor and friend.
