There was never any such "flip". This is just Dems trying to distance themselves from their past. They are the same party they've been since the 1860s.
What "multiple racism acts"?
Biden's besty in Congress was Robert BYRD (D) of West Virginia, an Exalted Cyclops(whatevethef**kthatis?) in the KKK.
Biden has been a racist for decades and continues to be one now.
The rest of your post is just more pure bullshit.

That comment indicates that you believe that she was kicked out of the party, you silly little child.
Don't get angry at me on account of YOUR ignorance, Skippy.
She was not kicked out, you epic ignoramous.
She was removed from the committees she served on.
What you don't know about US politcs would fill volumes.
