I'm not gay myself, so my opinion doesn't hold much weight, but there are people in this thread that are gay which don't see this as homophobic.
So by that logic, the only people who should be able to discuss in this thread are gay people. Yes?
So I just have to say that as a straight dude, while people have disagreed with me in this thread, I feel utterly unoppressed here. Yes, what I say has less weight, but that's okay. It's also not the same as not being able to talk.
I can explain why this, to my understanding, might have been seen as offensive by others. I can explain why I think it could be harmful. I can talk about how you should understand that a fictional world is created by real people and thereby anything that exists or happens within it is understood as a deliberate choice. I don't think anyone's ever gotten upset at me for doing these kinds of things.
But I'm not free to tell gay people that they aren't oppressed when they try to explain to me that they are. It's not up to me to decide what they feel about things. That's not a painful thing for me to have to give up.
