The most dangerous Muslims in America may be black converts to Islam, according to a shocking new poll by the Pew Research Center

African-American Muslims tend to hold the most violent views among U.S. Muslims surveyed by Pew in a new poll. Fully 28% of U.S.-born black Muslim respondents said that suicide bombings and other violence against civilians can be justified sometimes or at least in rare cases. That compares with 9% of foreign-born Muslims who hold the same view. Pew also found that 11% of black Muslims living in the United States have a favorable opinion of Al-Qaeda – more than double the share of U.S. Muslims overall who hold that view. Another 21% of black Muslims hold only mildly unfavorable views of the terrorist organization responsible for attacking America in 2001; while 56% of that segment of the Muslim population hold very unfavorable views. The survey results are troubling, because U.S. officials say that Al-Qaeda in recent years has stepped up its efforts to recruit African-Americans to target the homeland for terrorist attacks. English-speaking blacks do not fit the prevailing Middle Eastern terrorist profile, officials say, and Al-Qaeda recruiters believe that they have a better chance of slipping through security checkpoints. A growing number of black converts have been radicalized in prison or by Islamic websites, officials say.
