Egypt, a majority Muslim country, has the good common sense to outlaw the Muslim Brotherhood. CAIR is its American affiliate and we allow it to operate openly. Why is that?
Because, according to our esteemed President, being logical like that is “not who we are.”
Actually, in addition to CAIR, there are about 30 Muslim Brotherhood affiliates in the US and the Muslim Student Association (MSA - more chapters than the College Republicans and College Democrats combined), the Islamic Society of North America (ISNA - responsible for enforcing the Wahhabi doctrine in American mosques)) and the North American Islamic Trust (NAIT, which owns all mosques in the United States) are preeminent among them.
