There are serious differences between German or Italian fascism and Hamas' Islamism. But these are largely intellectual and academic distinctions. As a social phenomenon, the Palestinians voted for politicians such as Mrs. Farahat. She belongs to a brutal, terroristic, irredentist, militant organization dedicated to restoring national pride at the expense of exterminating millions of people, who just happen to be Jews. This was no secret, and it is a form of condescension bordering on infantilism to assert that the Palestinians didn't know what they were voting for. If the new government had the means, it would be Palestine's willing executioners.
Recognizing this fact doesn't automatically mean we should treat the Palestinians like cartoon villains who can never change. That's as foolish as assuming they didn't know what they were getting when they cast a ballot for Mrs. Farahat.
