RACISM !
Don't ever dare to think that racism can EVER end.
Don't ever think that Democrats are not the heart and soul of racism, because they are.
They won't let racism end, because it's the last remaining thread that connects them to power, or so they believe.
Who would have ever thought that the end of racism would only be possible when the Democrat Party becomes nearly extinct? Okay, that is rhetorical
Obvious answer: Anyone who has paid attention to history!
(which on a related note is why they're trying to erase it)
The real question: What can accelerate this in order to allow the Democrats to put some new planks into their platform and become relevant again?
