The FBI is justified. In America we have freedom of religion, and freedom of government if we change government in lawful ways. The Communist and Nazi Parties in America are attempting to change government in lawful ways. Islam is a violent government masquerading as a peaceful religion - http://www.thereligionofpeace.com/quran/023-violence.htm. Islam would change American government in ways not lawful. Unfortunately, most people in America, Muslim or otherwise, don't know this. What's an American Muslim going to do when his Islamic government calls on him to become violent, and kill his non-Muslim friends around him? Drop Islam? Get executed by his faithful brother Muslims for not obeying his/their religion? Or kill people who aren't Muslim?
