But if it prohibits discrimination based on gender identity or expression, doesn’t that cover everyone? Doesn’t it protect a woman from being fired because her boss thinks she should use more make-up? Doesn’t it protect the guy who is harassed at work because his co-workers think that real men don’t wear earrings, or pink shirts, or whatever?

These regulations are usually sold as protections for a small beleaguered minority, but I think they actually benefit a much larger segment of the population.
