From the study
"What it Means to be an American:Attitudes in an Increasingly Diverse America Ten Years after 9/11". Document is in PDF format and I didn't take the time to re-format excerpts it so paragraphs below are somewhat choppy. The entire study is worth the full read.

Most religious, racial and ethnic groups are viewed relatively favorably in the
U.S. although most Americans do not hold strongly favorable views. More than 8-
in-10 Americans say they have a favorable opinion of African-Americans (89
percent) and Hispanics (82 percent). More than 8-in-10 Americans also report
holding favorable views of Catholics (83 percent) and Jews (84 percent), two
groups once the object of widespread prejudice in the country. Mormons are
viewed favorably by two-thirds (67 percent) of the public, and a majority of the
public also reports holding a favorable view of American Muslims (58 percent).
Atheists are viewed least positively of any religious or ethnic group with less than
half (45 percent) of the public reporting a favorable view and nearly equal numbers (46 percent) reporting an unfavorable view.

More than 8-in-10 Americans in all major Christian groups say that Christians
who commit violence in the name of their religion are not really Christian,
including 86 percent of Catholics, 85 percent of white evangelical Protestants, 82
percent of white mainline Protestants, and 81 percent of black Protestants. More
than two-thirds (68 percent) of non-Christian religiously affiliated Americans say
that a self-identified Christian who commits acts of violence in the name of
Christianity is not actually Christian.
White evangelical Protestants stand out strongly from other major religious
groups in evaluating the religiosity of a self-identified Muslim who commits
violence. Only roughly 4-in-10 white mainline Protestants (41 percent), Catholics (39 percent), black Protestants (36 percent), and non-Christian religiously affiliated Americans (35 percent) say a self-proclaimed Muslims who commits acts
of violence in the name of Islam is really Muslim. In contrast, nearly 6-in-10 (57
percent) white evangelical Protestants believe that self-identified Muslims who
commit acts of violence in the name of Islam are really Muslim.
