I agree wholeheartedly that Christians must show compassion and the love of Christ towards homosexuals. The self-righteousness and hatred that often motivate violence and ridicule towards gays and lesbians should have no place in church life. I am ashamed of some Christians' judgementalism on this issue. Surely both promiscuity and the nature of specific sexual acts are important risk factors. The fact that the incidence of anal cancer among gay men is now greater than that of cervical cancer in women is not readily explained by promiscuity alone.
Suicide is always a great concern.
I have no doubt that homophobic bullying, violence and verbal abuse all contribute to the self-loathing that drives some gay men to take their own lives. This is deplorable. However, the heartache and rejection accompanying the high promiscuity rates in the gay world are just as likely as homophobia to underlie the higher suicide rates. I do not know of any peer reviewed study that settles this issue one way or the other. We cannot compromise on what God says about sex.
