Well I’d guess that each generation of Democrat has to be the first and greatest EVAH!!!!! and Bill isn’t on board with it since he was the first black president and BEST PRESIDENT EVAH!!! as told him by legions of kneepad wearing interns.
So since Barry is more Arab and White than genetically Black, he has issues about his actual slave blood content. Which, if memory serves, Bill actually has more. Which is more important than content of character when these things collide. In honor of MLK.
So it’s just one big happy clusterfork.
If zero had any slave ancestors we would've heard about it once a week since 2008.
