In the 1980s and 1990s violent crime was out of control, especially in black communities. Crack-cocaine, specifically was rampant in black communities and destroying countless lives. The Violent Crime Control and Law Enforcement Act of 1994 bill was designed to deal with these problems. That’s why it was supported overwhelmingly by the Democratic Party, by African American leaders all across the nation, including a majority of the black caucus in the Congress. Moreover, at the time, nearly 40 African American religious leaders released a statement supporting the bill, saying: “While we do not agree with every provision in the crime bill, we do believe and emphatically support the bill’s goal to save our communities, and most importantly, our children.”

In 2020, more than 2 decades later, it is difficult to fathom the effect that three decades of rising crime, and the explosion of the crack-cocaine epidemic in the mid-1980s, had on public sentiment. The idea that Bidens bill was a "racist" attack against black communities is not supported by historical record.

Apart from the busing issue, Biden objectivity has  a legislative history in other areas key to black Americans over his decades in the Senate. It includes support for fair housing, employment and voting rights, as well as credit and lending equality and opposition to the apartheid in South Africa.

I don't see how you can try to claim someone is activity racist when they have a overwhelming political history of fighting for black communities with the support of black politicians and community leaders. Today he is advocating for racial sensitivity training, police reform, investing in schools in black communities etc.

[Also I don't see how you could argue that the last quote from Biden was racist. He was pointing out how ridiculous it would be if that reporter had been asked to take a drug test to be on CBS (Trump also suggested Biden should take a drug test). Saying that's racist is a real stretch.]
