It does not dictate that they are not worthy of being part of their community, they are supposed to be welcome at church. However the church is not to sanction same sex unions and partnerships, which go against God's design and intent.

For the record I never lived in an American society where Christianity is associated with right-wing fiscal values, that always flew over my head. I live in a society that used to be practically a Catholic theocracy where people were taught all these things, such as relishing money being evil, etc.
It might look like a whole lot of energy being spent on a single issue among many others, but when the definition of something major like our expectations of what is marriage and what is a family are being changed, it will resound in a lot of people's minds and they will step up.
Since your god doesn't in fact exist (or at least you have zero evidence that it does) and homosexuals on the other hand do, I reckon that homosexuals take priority. You can believe whatever fantasies you like, as long as long as they don't impact on other people's lives. But, when they do you need to be very sure that you are right - and your Christian religion has no more right to be taken as a serious attempt at truth than any other religion or the flying spaghetti monster for that matter. We need to relegate religious discrimination against minorities to the past where it belongs and noone should have the right to tell any other adult what they can or can't do in the privacy of their homes.
