Somebody on FR coined a term to describe the unholy axis between the Left and Islam in America: the “Hammer and Crescent”.
They’re both totalitarian, hate Christianity, the West and Israel, and preach violence against those who resist their agenda.
Our local mosque was an old storefront with “Islam Is The Solution!” painted on it. A friend who is a rabbi remarked, “Then it must be a really stupid question!”

David Horowitz had it spot on in 2004, with “Unholy Alliance: Radical Islam and the American Left.”
