I had told Elders, COs and other people that I would rather not say. I told some family members and chose not to tell others. I told some people in my halls and chose not to tell others. In the gay community this is not all that uncommon. I have plenty of gay friends who never were witnesses or don't have religious family members, who they have never come out too. Coming out is a very personal and private matter for every gay person and they have to tell the people who they want and not tell the people they don't want to.
I never felt a bit of prejudice by the people I told. I didn't tell everyone, but that was my choice. And beyond the people I told, at least as far as I know, no one else knew.
I understand you will choose who you may wish to come out to and who you may not - the extent of your decisions on this was not the point of question. It was more based on surprise that you did not feel any prejudice at all.
TBH, I can imagine them (elders/CO specifically) being outwardly understanding and not actually making a big thing of it but only really if they felt comfortable that you were not "practising" (for want of a better phrase), if they felt a sense of penitence or shame from you that you were simply battling emotions. I am 100% sure that if they felt you were in or actively seeking a homosexual relationship then you would be looking at the threat of judicial action.
Regardless of individual responses there is no doubt that any gay person wishing to be a Witness has to make a stark choice - suppress their emotional desires and opportunity to find happiness with a partner or become someone not welcome at the hall. There is zero option for anyone to be sexually active (or assumed to be so by the elders) gay person and be an active Witness. When push comes to shove, the people you came out to would have to choose the party line above whatever their supposed acceptance and non judgemental, lack of prejudiced attitude to you was to remain Witnesses themselves.
