I just got from Amazon.com my copy of Jamie Glazov's book, "United in Hate: The Left's Romance with Tyranny and Terror." I also heard Glazov on KSFO radio (San Francisco) talk about the book.
Glazov notes that the Left always supports the tyranny du jour. First they supported Fascism; then Soviet Communism; and today they support violent Islam and Jihad. This is not an exaggeration. Jonah Goldberg, in his book "Liberal Fascism," gives historical facts about the liberal dalliance with fascism in the 1930s (they liked it -- a strong central, socialist government where the interests of the state superseded that of the individual. What's not to like?).
The left's romance with Soviet tyranny is something I observed first hand, having lived through a few decades of that history. Basically, they wanted unilateral disarmament, meaning, we would prove to the Soviets that we loved and trusted them by eliminating or severely reducing our nuclear stockpiles, thus making them feel secure and voila, they would eventually follow suit by reducing their nuclear capability as well. Furthermore, we wouldn't oppose their subversion and conquest of other nations because those nations would be better off under communism anyway. Some idiots even suggested that we send great sums of money to communist third-world despotisms who hated our guts. Sort of like Obama is doing today with regard to Hamas, pledging to send them almost a billion dollars.
Today radical Islam is the new fad. Leftists throughout the West are importing millions of hostile Muslims and changing their laws and customs to suit the newcomers. The Left hates Jews and so admire the fanatical Islamic anti-semitism
