If Biden was really racist, he would not have accepted to be Barack Obama's running mate in 2008.
That doesn't say anything about whether or not he is racist, it just says that he didn't turn down a golden opportunity. There are plenty of racist people who don't allow their bias to interfere with their career.
Yep. John Wayne was an avowed white supremacist but all people of color who worked with him testified that he was a consummate professional and treated them with nothing but respect and kindness.
Okay, now care to find any evidence of Biden being an "avowed white supremacist", or anything even close to that?
People are grasping at straws here, and I don't even like Biden
