Just a reminder. Biden started is wntire career with one purpose in mind... keeping segregation alive. I will never vote for the most racist politician alive today... never.
Wasn't this quote debunked during the last US election, and easily checked before amplifying this misinformation?
by the way, aside from your own link that proves the post I boosted was accurate, here is the actual first-hand source.
In 1981 desegregation was under way through an effort to bus black students in all-black schools to segregated white-schools so they can desegregate them and allow the blacks to get the same quality education as these better funded schools could provide.
He spent most of his early career trying to fight these and really all desegregation efforts still ongoing at the time. In fact, he was one of the most vocal segregationists in congress at the time.
Here is a 1982 Senate hearing in which Biden's testimony is recorded. Not only does he make it clear he opposes these desegregation efforts, but it is also the first time he used the "racial jungle" quote in some form and very clearly confirms that a very similar variation of the quote has been spoken by Biden as early as 1982.
