'Gayness' is far more than just sex, wild parties, and drugs. It hasn't helped that Hollywood has stereotyped to the point that mainstream society believes that all homosexuals carry some sort of STD (when in fact most gay men wear rubbers, and two, it is very difficult for two lesbians to spread an STD). The only way two gay men won't wear a rubber is if both are HIV positive anyway.
Also there are gays who live rather conservatively. They don't prefer wild parties, only drink socially with friends, would just prefer the company of their mate rather than having an all night sexcapade.
Whats sad is so many religious nuts think of homosexuality as a sin and treat it like a disease. Like if a church member is found to be gay, usually that member is pulled aside by the pastor and a couple of deacons and are told the 'clobber scriptures' and are urged to seek help immediately for their 'sin'. If the member refuses to seek help or 'cannot be cured' then the church usually votes to excommunicate them meaning they can still attend, they just do not have any 'rights' of a full member such as being able to serve on committees, teach Sunday School classes, assist with other ministries, or to have a vote in business meetings. But the apex of the excommunication is that that member is no longer allowed to partake in Holy Communion. They are 'cut-off' from God because of the 'sin' and therefore not considered 'in-fellowship' to take Communion.
When a homosexual is excommunicated one of two things generally happen.
1.) They leave the Christian community completely or
2.) They find an affirming church in their area where their sexuality is accepted completely and openly within the congregation.
