The early days of Donald Trump’s presidency have been an anxious time for many Muslim Americans, according to a new Pew Research Center survey. Overall, Muslims in the United States perceive a lot of discrimination against their religious group, are leery of Trump and think their fellow Americans do not see Islam as part of mainstream U.S. society.

At the same time, however, Muslim Americans express a persistent streak of optimism and positive feelings. Overwhelmingly, they say they are proud to be Americans, believe that hard work generally brings success in this country and are satisfied with the way things are going in their own lives – even if they are not satisfied with the direction of the country as a whole.

Indeed, nearly two-thirds of Muslim Americans say they are dissatisfied with the way things are going in the U.S. today. And about three-quarters say Donald Trump is unfriendly toward Muslims in America. On both of these counts, Muslim opinion has undergone a stark reversal since 2011, when Barack Obama was president, at which point most Muslims thought the country was headed in the right direction and viewed the president as friendly toward them.

In addition, half of Muslim Americans say it has become harder to be Muslim in the U.S. in recent years. And 48% say they have experienced at least one incident of discrimination in the past 12 months.
