Allow me to add my voice to the chorus. Welcome. You have clearly made a difficult choice. I love the image of you tacking your DA letter on the information board, like Martin Luther nailing his treatise to the door of the church. The hatred of homosexuals in the WTS, and in the bible in general, was something I had a hard time with when I was a believer. I always imagined trying to make the choice to be gay, and I couldn't imagine under what circumstance I could do it. I then tried to imagine if the converse was true, if there were those for whom making the choice to be heterosexual was equally difficult.
I have known several gay Witnesses, and it was as plain as the nose on their faces. One in particular I was good friends with since we were both around fourteen. Everyone made jokes about him being gay. When he got older, he bought a Miata and went into the fashion industry. It wasn't long after that that he was disfellowshipped for homosexuality. He is now reinstated and "happily" married to an obese woman. I feel very sorry for him.
Another man I knew personally, although he was much older, actually had his experience recorded in the Awake magazine ("Something Worse Than Aids" 4/22, 1989). When I knew him it was after the events of that magazine, yet he was clearly gay. Thankfully, before he finally succumbed to the disease, he at last told the Elders that he "was gay and theirs nothing he can do about it". I don't know how his final months were, but I hope he found happiness in not having to pretend anymore.
Congratulations on finding the courage to break free. I wish you well and look forward to your future posts.
