While I am not going to classify all Muslims as terrorist, I do have to say that I have not seen any type of outspoken criticism within the community over all that has been happening in the past few decades (centuries ).
Then you haven't been paying attention. CAIR (Council on American-Islamic Relations) has been doing a lot of this kind of thing, as have other groups.
""American Muslims, who unequivocally condemned today terrorist attacks on our nation, call on you to alert fellow citizens to the fact that now is a time for all of us to stand together in the face of this heinous crime."
-September 11 letter to President Bush, signed by the leaders of the American Muslim Alliance, the American Muslim Council, the Council on American-Islamic Relations, the Muslim Public Affairs Council, the Muslim American Society, the Islamic Society of North America, the Islamic Circle of North America, and the Muslim Alliance in North America. These groups represent most of the seven million Muslims in the United States. "
Can you name me one major political leader within the Muslim community that condemns the acts of terror and violence that has been going on ?
"Hijacking Planes, terrorizing innocent people and shedding blood constitute a form of injustice that can not be tolerated by Islam, which views them as gross crimes and sinful acts." --Shaykh Abdul Aziz al-Ashaikh (Grand Mufti of Saudi Arabia and Chairman of the Senior Ulama, on September 15th, 2001)
"What these people stand for is completely against all the principles that Arab Muslims believe in." --King Abdullah II, of Jordan; cited in Middle East Times, Sept. 28, 2001.
Can you name me one Muslim leader that talks about tolerance for the Gay Community? Can you name me one Muslim leader that has taken a stand for the rights of women? Can you name me one woman that would be considered a Muslim leader? While I see thousands of protesters on television calling for blood shed and war, where are the thousands of Muslims that take to the streets and call for an end to the violence? Name me one country (Iran, Iraq, etc) where I could go there and openly in the street criticise the government? We can do that here in the United States (tell me one person that has not seen or heard something making fun of Bush).
Irshad Manji is a leader of the Muslim LGBT movement (and she's a woman). I would point out, too, that America is not all that tolerant of gay people either. As to Muslims taking to the streets for an end to violence, I suggest you go to CAIR's website. There are some instances of street protest, but they've also been involved in far more effective means of social change.
Whether or not it is safe to criticize the US government is a matter of opinion, and varies greatly on how far your criticism goes. But if you want an example of protest in places with large Muslim populations (it's not fair to compare us to a theocracy - that's an entirely different form of government), look at southeast Asia.
