The ideology of the left is anti-American. They are anti-Israel because of America. They are pro-muslim because they are anti-American. They hate cops, Christians. The Palestinians are using them latching on the the anti "colonist" theme to make their blood thirsty jihad sound like a fight for liberation instead of a fight for enslavement and genocide - as is the ultimate goal of all islamist movements. They love the useful idiots in America and Europe. Perpetrating fraud upon Western liberals is their greatest source of power and faux legitimacy.
