Heterosexual promiscuity in the world today has done far more damage to society than homosexual promiscuity has. Homosexuality is no more "gross" than heterosexuality. It is a way of life for some people.  While I think it is not a healthy way of life, I am much more convinced that it is wrong to belittle people who  happen to live that lifestyle.  
Politics is seldom simple. But the truth usually is.
