LONG BEACH, Calif. -- The beating of a gay man outside a bar resulted in the arrest of four Camp Pendleton Marines and was being investigated as a potential hate crime, Marine Corps and police officials said Wednesday.

Long Beach police said a preliminary investigation found that the four Marines attacked the man just after leaving the bar. Two other men who tried to help the victim were also attacked, police told the newspaper.

Long Beach police Cmdr. Joe Stilnovich said at least one of the suspects used derogatory terms regarding the victim's sexual orientation, U-T San Diego (bit.ly/NSIhC0 ) reported.

The Marines were arrested just after the incident. They have since made bail and returned to their units, Camp Pendleton spokesman Maj. Manuel J. Delarosa said. Military officials were assisting Long Beach police and the Marine Corps was conducting its own probe, he said.

"This is an isolated incident," Delarosa said. "Committing any hate crime is unacceptable behavior and is not tolerated in the Marine Corps."

The victim was treated at a hospital for non-life-threatening injuries, Long Beach police spokeswoman Lisa Massacani said. The two others who tried to help the victim suffered minor injuries.

Neither Massacani nor Delarosa gave specifics on why it was being considered a possible hate crime.

Arrested were Lance Cpl. Lewis Serna; Pfc. Thomas Pentek; Pfc. Sean Miller and Lance Cpl. John O'Leary. Authorities were trying to determine each person's role in the assault, Stilnovich said.

The four Marines could not be reached for comment on Wednesday.

  • Bryan Fischer: Gay Adoption Is 'A Form Of Child Abuse'

    The American Family Association evangelist sounded off on a controversial study about gay parenting, which claimed to find disadvantages for children raised by same-sex parents. Fischer spoke about the study on his "Focal Point" talk show, labeling adoption by same-sex couples as "a form of child abuse." Of course, Fischer didn't stop there, making a point to condemn gay sex, too. "The sex that's involved in homosexual behavior -- it's unnatural, it is immoral and it is unhealthy," he proclaimed.

    "It is altogether right for a rational culture to discriminate against homosexual behavior," Fischer said. "I am saying, yes, that's exactly what DOMA does and it should...because [homosexuality] is not a benign alternative to heterosexuality...we ought to discriminate." Right Wing Watch also noted that Fischer's declarations echoed those made in a blog piece he wrote last week, in which he compared LGBT people to the disturbing spate of cannibalism cases currently making headlines.

"Build a great, big, large fence -- 150 or 100 mile long -- put all the lesbians in there," Worley suggests in the clip, reportedly filmed on May 13. "Do the same thing for the queers and the homosexuals and have that fence electrified so they can't get out...and you know what, in a few years, they'll die out...do you know why? They can't reproduce!"
