All of them are anti-gay except Bob Dornan, who I don't know anything about except that he was a Congressman from California.
http://en.wikipedia.org/wiki/Bob_DornanAlso, check this out (from a different website):
"Brian Bennett was a long-time aide to Dornan. According to Bennett, Dornan was like a father to him, until Bennett told Dornan he was gay. The two haven't spoken much since. Dornan is an outspoken opponent of gays, citing religious reasons. Bennett, who is both a Catholic and a Republican, spoke emotionally of the day he found out the Catholic Church has a history of tolerance to homosexuals. It was obviously a relief for Bennett to discover that he might be able to reconcile his beliefs and his sexuality. Whether or not he was able to do that is not really discussed in the film. The current leadership of the Catholic Church accepts homosexuals, but it also deems any sexual acts outside of marriage to be sinful.
Bennett clearly wants to renew his friendship with Dornan. Dornan's adamant opposition to homosexuals is illustrated by several taped speeches in Congress and elsewhere. Dornan, who is a Catholic, seems to greatly exceed the guidelines of his own religion's catechism in his opposition to homosexuals. The catechism reads, in part, "The number of men and women who have deep-seated homosexual tendencies is not negligible. This inclination, which is objectively disordered, constitutes for most of them a trial. They must be accepted with respect, compassion and sensitivity. Every sign of unjust discrimination in their regard should be avoided. These persons are called to fulfil God's will in their lives and, if they are Christians, to unite to the sacrifice of the Lord's Cross the difficulties they may encounter from their condition." Whether or not the Dornan and Bennett can ever be friends again is an open question at the end of the film."
