I have no problem with the idea itself, Adrian. Any religious institution is free to establish laws and rules for itself. I myself am under 4 vows, and most likely many people don't join our little organisation because of one of those vows, or something else. It takes 5-10 years of training to join, lots of personal counseling, etc. If, during that process, something is encountered, we merely suggest joining a more liberal sect or school within Hinduism. We don't ask anyone to change their behaviour
What bothers me is the contradiction of saying that you're open to all, loving of all, and then do this 'but .... thing. But maybe I'm mistaken too. maybe some Baha'i' counsellors, if they exist, would recommend to a gay that they shift to another more liberal Abrahamic Church.
Some of the hardest situations, for anyone in a gay repressive religious organisation, though, is for children who are born into it. For a person just looking at it from the outside, they can choose to not join at all, whereas a person born into it suffers a lot of personal loss (friends, maybe family) by renouncing it.
We all have our journey and struggle in life. In my twenties and into my early thirties I went through a long period of celibacy. As I searched for the truth and meaning in life I had to live in accordance with my highest values and had to sacrifice the lower nature to eventually embrace the higher nature. This was for a period of over 10 years. I think if we are serious about the spiritual path we have to make sacrifices. We can't simply follow the standards and practices of those around us, and for me that also meant abstinence from intoxicating substances including alcohol, and avoiding backbiting and gossiping.
Some that chose to become Baha'is have been through a similar challenging time, others have not. Those who become Baha'is are free to leave including children of Baha'i families and there is no shunning because of that. That is not the Baha'i way.
In regards to counselling, I practiced psychiatry for 7 years so often had 2 or 3 long term psychotherapy patieints that I would be seeing long term as well as the general work within mental health services. The art of counselling is to be able to reflect back to others what they are saying in a way that they can see themselves in a different more positive light that enables and empowers them to find their own path. Counselling doesn't involve tellling others what to do, imposing ones own vaues on others, or manipulating.
It is my sincere belief that some people who identify as homosexual have heterosexual leanings too. I also believe that for some people, especially when younger, sexual orientation is more fluid and not immutable. I also believe one of the major challenges for many of us, is to become focused on the well being of others and give less attention to persuing and gratifying our sexual urges.
