Americans Still Distrust Atheists and Muslims. The Reasons Why Are Changing.

About 40 percent of Americans say atheists “do not at all agree” with their vision of America, according to a new study from sociologists at the University of Minnesota who compared Americans’ perceptions of minority faith and racial groups.

But the study marks a grimmer milestone — Americans’ disapproval of Muslims has jumped to 45.5 percent from just over 26 percent 10 years ago, the last time the question was asked.

And “nones” — those who say they have no religious affiliation, but may also have spiritual or religious beliefs — are also unpopular. This is significant because nones now make up one-third of the U.S. population.
