They will never learn to let it go

What are you trying to say? That nobody in the world is racist?

Racism in the US was at historic lows.

But then occupy wallstreet and Obama's extremely racially divisive rhetoric became a focal point for the nation.

Which, to borrow leftist terms, means racism in the modern USA is a social construct. One which only the left has benefitted from.

This nation had its first black president and a lot of conservatives hated that, and you're going to blame Obama for the rise in racism after he was elected?
