That one really bugs me too. Mostly because it comes from LGBTQI people the most. I understand about being 'blah' and kind of inconspicuous. In my experience, it's more about not being seen by potential attackers or competitors (women and men).
This doesn't even bother me anymore. In a world where everything is basically take at face value, even I have a hard time figuring some people out.
I was at a bar once with my very butch poster child best friend. A guy came up to me and asked, "Okay, so I know she is, but are you?"
Bitch please. We were in a gay bar for God's sake.
It does come in handy at times though - i.e. attackers, etc.
