People who wrongly believe President Obama is Muslim are "psychopaths", according to a sermon Sunday from Rev. Jeremiah Wright in Little Rock, Ark.

The president's controversial former pastor told the congregation at New Millenium Church that Obama is being ostracized for opposing the "military mindset." During his sermon, Wright also criticized supporters of the war in Iraq and defended former state Court of Appeals Judge Wendell Griffen for speaking out against it.

"Go after the military mindset ... and the enemy will come after you with everything," Wright told the packed church, according to the AP.

"He will surround you with psychopaths who will criticize you and ostracize you and put you beyond the pale of hope and say 'you ain't really a Baptist' and say 'the president ain't really a Christian, he's a Muslim. There ain't no American Christian with a name like Barack Hussein,'" he added.

A recent poll shows 18 percent of the public thinks President Obama is Muslim, an increase of 7 percent over March 2009. The proportion of people who believe he is Christian has shrunk to 34 percent from 48 percent last year.

Obama cut ties with Wright and left his Chicago church after some of the reverend's more controversial statements became a source of criticism during the 2008 presidential campaign.
