African-American Muslims tend to hold the most violent views among U.S. Muslims surveyed by Pew in a poll released this week. Fully 28 percent of U.S.-born black Muslim respondents said "suicide bombings and other violence against civilians" can be justified sometimes or at least in rare cases. That compares with 9 percent of foreign-born Muslims who hold the same view. Pew also found that 11 percent of black Muslims living in the U.S. have a favorable opinion of al-Qaida more than double the share of U.S. Muslims overall who hold that view. Another 21 percent of black Muslims hold only mildly unfavorable views of the terrorist organization responsible for attacking America 10 years ago; while 56 percent of that segment of the Muslim population hold very unfavorable views. Poll stunner: These American blacks OK with violent attacks How will you know which black Americans are Muslim?
