"Putin Exposes the Secrets of American Liberalism: Liberals just hate it when someone uses their own arguments against them"
There is an unspoken sub-text at play here: what President Putin said in his column is pretty much what American liberals and leftists have been saying about the United States since the 1960s. From the standpoint of American liberals, there is nothing the least bit new or controversial in anything Mr. Putin wrote in his column. He is merely hoisting President Obama and his liberal friends by their own ideological petard.
I think that's right. But I think there's also another dynamic at work: Liberals love to mock but absolutely hate being mocked. When I was a kid this was called "They can dish it out, but they can't take it."
