Let's get this out of the way right at the start: No one is mistaking Matthew Foerstel for a "transgender person" for lack of the better one-word noun I'm sure someone will come up with very soon. He's clearly just a male pervert going where he's not supposed to be. I don't even think he's claiming to "identify as a woman."
But last week, Target took a step toward completely erasing the distinction between men's bathrooms/dressing rooms and women's bathrooms/dressing rooms when it told everyone to just use whichever one suits their, um, "gender identity."
