OK so instead of “on their own” - would “not allowed to step foot in a church” fit? Are people who have non-homosexual mental disorders allowed?
Having a mental disorder does not necessarily mean a lack of self control. Someone might have anger problems and want to slap everyone he/she disagrees with. To act on that desire would be a problem, right? In the same way, acting on the mental disorder of homosexuality is a sin.
You said, “It is wrong to assume the church is positioned to treat homosexuals....or for that matter alcoholics or gluttons. All should be getting the professional help they need first and foremost.”
I can’t believe you really believe this. First of all, the church is chock full of FAT people, as well as people who spend excessive money on vanity while they thumb their nose towards a world of people who are hungry, thirsty, enslaved, and in pain. Gluttony is rampant in the American church. Secondly, its sounds like you are saying that alcoholics (and other addicts) can be invited to church, as long as they are receiving professional help first and foremost. So why would that not apply to homosexuals?
