A man capturing video at at rally in Boston was assaulted and threatened. So how is an event in Boston relevant to Northern Virginiastan?
The event, called the "Justice for Palestine and Lebanon Protest," but actually a pro-Hizbollah rally, was sponsored by the Muslim American Society, which is based in Falls Church (which should be renamed Falls Mosque). The Muslim American Society is the U.S. front for the Muslim Brotherhood, the ideological forebearers of Al-Qaeda (Ayman al-Zawarhiri was a "brother").
Media hog (and yes, my choice of words is deliberate) Mahdi Bray claims that MAS rallies are always peaceful. The Muslim Link newspaper covered a smaller demonstration of 15-20 people including Mahdi Braying Ass protesting Israel's entry into Gaza outside the Embassy of Israel:

These events show the collusions between Islamicists and leftists.
