Yes, that makes sense.
Of course, coming out as bi (for example) has social, political, personal, economic, religious, etc. implications that saying, "I'm a mama who breathes' doesn't. And I know for me at least, saying 'I'm bi' whether or not I express any bisexuality openly, has ALOT to do with overcoming my religious upbringing and various ick gender, sexual stereotypes I've learned growing up.
Sometimes, though, when a friend does come out as bi, I think, 'of course you are!' I hope that doesn't sound harsh. I don't mean that I know what people's sexuality is...just that, imo, we have a long history as bisexual beings in the human race.
And every intelligent writer and thinker I've ever read was openly bi!
It's a wonderful group to self ID with.
