You're not wrong. Eight years of Obama was enough for the racist cancer in the heart of American culture to finally metastasize and start to consume the body politic.

It doesn't help that Donald Trump basically shares many of those extremists' beliefs, prejudices and conspiratorial mindset (he's the man who made birtherism a thing,) and so does nothing but fan the flames and grant them an air of legitimacy. But he's more of a symptom than a cause IMHO.
