And of course it's also related to the problem of pride and shame wrt group identification generally, the way the someone whose actions you aren't in any way responsible can make you feel ashamed, the way the status of that group can make you insecure when you have no reason to be. I think that's related to why I feel more insecurity about being a white foreigner than liking girls. There's something I don't like about that status that I don't give a shit about for bisexuality, even if I did have a girlfriend and I got all the shunning and/or awkwardness that would likely happen in a traditional place like Zhengzhou. I'm not sure I'd go so far as to say I'm proud of it (doesn't seem like an accomplishment, exactly), but I certainly have no shame about my sexuality. Just a thought.
