People have been indoctrinated, especially in this country with the thinking that we cannot offend people, so we must tolerate their behavior....Given this inch, they take the mile by saying we must accept their behavior in all aspects of what we do in organizations and change our traditions accordingly or perish (Boy Scouts and Marriage are a good example of this).
I don't really think its as much an organized push as it is a common way of thinking amongst homosexuals.
The Baptists are way behind the "tolerance curve", so an event like this is not possible at the moment. Because of traditions and the power structure of the Catholic Church, it remains unadvertised to an extent, though there have been cases and seem to be more all the time where people want the traditions of the church changed. I think the Church of Christ and Assembly factions don't have these issues because many of those members have run TO those groups, not started out there, due to the changing of the older factions.
I think if you study the history of the Episcopal Church, you would see it is a slow chipping away of the standards day by day, year by year. Not over the last 10 years, but probably more over the last 100.
It is obvious to me that this new Bishop is not working in colusion with "The Homosexuals", but is instead thinking of himself in this situation. It's all about him. Look at his life, and you will see that he has adjusted his life by his rules, not God's. He was married, with a child, left his wife for a man. He has convinced them that, depspite the promises he made in the past in regards to fidelity/trust/etc, his action to leave his family is ok. (and has used them as pawns in this latest event). He has kept his religious standing instead of understanding its ways were not for him, and has pushed people to be "tolerant" of him so that he can maintain and increase his power within the organization. Now its at the point where to obtain more power for himself, he must fracture his Church. He certainly does not seem to have a problem with this.
