to expand a bit on the “Sua-point”, back in my liberal college days, I recall a conversation I had w/a woman regarding her being a lesbian. I, in my own, “I’m so advanced” way, said “gee, that’s your business, no one should judge you about it 'cause it isn’t their business etc etc etc”.
and she set me right.
For her, conversations with family, long ago school chums, co workers, the general public, would always have, at it’s core, a different framework, “do they know, should they know, should I admit”.
On a daily basis, we have casual encounters, deeper conversations etc with all manner of people. and some basic assumptions are often made. We discuss the latest movie, adding in “Gee, and Mel shows his butt”, expecting that the other females will agree that it’s a good thing and the males will be less enthusiastic. We ask “are you seeing anyone”, when we know the person to be single, and suggest potential mates, with the default setting as “heterosexual”. (that is to say, that I doubt that many of us would assume there is a potential for a gay or bi orientation, unless we were already aware of it).
and to the extent that those who do not have a heterosexual orientation have to go through mental gymnastics or pronoun terrors in order to engage in these conversations, then that is the extent that “sexual orientation” defines us.
IN other words, it is difficult for the ‘default setting’/majority to get a sense of how pervasive assumptions about sexual orientation are. HOlding hands w/loved ones, gentle goodbye/hello kisses, even the assumption that you’re ‘a couple’, routinely impact our daily lives.
