What exactly is your point? Homosexuality is forbidden among JWs, that's why it's relevant on an ex-JW forum. How else can we talk about something without labelling it? Words are labels and labels are how we communicate. The word gay is the commonly accepted term for homosexual men.
What are you advocating, that we don't talk about the topic at all? Why would you want to stop people from talking about it? You're welcome to stay away, but it's not your place to shut down other people's conversations.
