I've been closeted more times than I can mention...in some cases I understand it, and in some it just pisses me off. Now, I'm a lesbian who is definitely out, and I will not voluntarily re-closet myself just because someone else is afraid of what they don't understand. The only way to change that fear is education, and I am young enough that I have the energy to do it.
I came out at 18; my mother outed me to my entire extended family; she also took it upon herself to talk shit about my wife, who I had introduced her to, and later told her we were together, and later told her we had gotten married! My mother took it upon herself to call my wife's father, and talk about the two of us behind our backs. She got angry at me once and made discriminatory comments, and I called her on it. No comments since, but both my mom AND dad still try to avoid listening to me when I bring her up. Since they're helping me financially with school, I'm afraid to change my name legally (I've been married for almost 2 years and haven't taken her name yet). They ignore my wife, even though I keep prying their eyes open and making them accept it as much as possible. I can't force them, but I won't allow them to go into denial about it. It is what it is, and I'm not mincing words about it. I won't disclude her from conversations just so people will feel more comfortable.
Even at work, the discrimination. I don't disclude her there either. My life is what it is, and I would rather people leave it if they dont' like it now. I don't want to have to confront anyone 20 years from now about it.
My in-laws closet us for other reasons. They don't understand why we are together, and they don't think it's right that we are together, but they like us individually as people, and they've started to agree to disagree with us - meaning that they've started referencing our coupled status, something I never thought would happen. Their other children are under 15, and they all know about us, but it's not talked about in their house. Which is fine, but when they come to my house to play, we do have conversations and I do try to help them understand. I want them to know me as I am now, and not wonder why the hell I'm always at their house with their sister. They have started asking me questions, and I will answer them honestly (of course within reason), whether or not their parents like it. I'm not going to let my in-laws closet me in my own house.
So much more I could bring up, but you all have said it.
