Liberal HBO’s Real Time host Bill Maher was on the right track when he said Friday that the Democratic Party has a new “bullshit purity test” which says its elected members must, under no circumstances, support the only good government in the Middle East — Israel’s. But he fell off when he said it was the consequence of “shallow thinking” among liberals.

It’s not “shallow” and it’s not even “thinking.” This is the way political and cultural battles are now fought in America. That’s the entire point of my new book: Privileged Victims: How America’s Culture Fascists Hijacked the Country and Elevated Its Worst People.
