To state that homosexuality and homosexual behavior are against the will of God and to deny that such things are deserving of equal civil and moral status with heterosexuality and heterosexual behavior is, to the mind of such people, victimizing and diminishing homosexuals. Don't expect that to change soon.
So are murderers victimized and diminished when one "states" that murder is wrong? In a free society, people have a right to believe and state that homosexual activity is immoral. One can argue about whether it should be criminal, but one has a right to believe it immoral. And to state so in a loving way is to help those with a tendancy to this specific sin to leave a sinful and harmful lifestyle. Just as a statement that adultery or divorce is wrong might make people inclined to those particular sins stop and think.
