More than half of Americans lack a basic understanding of Islam, while a sizable number hold negative views about the world's second-largest religion.
Most Americans think President Obama's pledge to "seek a new way forward" with the Muslim world is an important goal, even as good amount of number say that even mainstream adherents to the religion encourage violence against non-Muslims, according to a new Washington Post-ABC News poll.
The survey showed that 55 per cent of those polled said they are without a basic understanding of the teachings and beliefs of Islam, and most said they do not know anyone who is Muslim. While awareness has increased in recent years, underlying views have not improved.
About 48 per cent said they have an unfavourable view of Islam, the highest in polls since late 2001.
Nearly three in 10, or 29 per cent, said they see mainstream Islam as advocating violence against non-Muslims; although more, 58 per cent, said it is a peaceful religion.
Overall, nearly two-thirds said Obama will handle the diplomatic mission "about right". Nearly a quarter, though, said he will probably "go too far". Nine per cent said it is more likely he will not go far enough.
Republicans are also more apt than others to hold negative attitudes toward Islam, with six in 10 having unfavorable views, compared with about four in 10 for Democrats and independents.
Perceptions of Islam as a peaceful faith are the highest among non-religious Americans, with about two-thirds holding that view. Among Catholics, 60 per cent see mainstream Islam as a peaceful faith; it is 55 per cent among all Protestants, but drops to 48 per cent among white evangelical Protestants.
There are deep divisions in perceptions of Islam between younger and older Americans as well: More than six in 10 younger than 65 said Islam is a peaceful religion, but that drops to 39 per cent among seniors.
The Post-ABC poll was conducted by telephone March 26-29 among a national random sample of 1,000 adults. The results have a margin of sampling error of plus or minus three percentage points.
Muslims make up about 1 per cent of all US adults.
In his inaugural address, Obama extended an offer to leaders of unfriendly Muslim nations that the United States "will extend a hand if you are willing to unclench your fist."
