WASHINGTON (AP) -- A gay advocacy group is demanding that the Pentagon's top general apologize for calling homosexuality immoral.

In an interview with the Chicago Tribune, the chairman of the Joint Chiefs of Staff likened homosexuality to adultery. Marine General Peter Pace said the military should not condone homosexuality by allowing gays to serve openly in the military.

The Servicemembers Legal Defense Network says Pace's comments are "outrageous, insensitive and disrespectful" to the 65-thousand gays and lesbians now serving in the armed forces.

The group has represented some service members dismissed from the military for their sexual orientation.

Pace says he supports the "don't ask, don't tell" policy, which allows gays and lesbians to serve if they keep their sexual orientation private and don't engage in homosexual acts.

Pace says he was brought up to believe that homosexuality is wrong.
