I reject your premise entirely. And I reject any notion of the idea that anyone else, aside from the person in question, gets to make the decision on whether they're out or not. That is my final say in the matter.
That's not really much of an argument, and I can't imagine why. As a society we decide what information is hidden and what isn't all the time. Some cultures make women cover their faces even. And, that doesn't address the fact that some queer people cannot pass as straight.
Do you disagree generally with US law that public figures do not have the same rights to privacy as other people?
