Enforcement

[ReineD]

The one that I had in mind when I mentioned this happened in a restaurant in downtown Detroit. As I remember, the woman didn't look particularly masculine, ..

You be the judge. I found the article: http://www.advocate.com/business/201...oking-man-sues

She wasn't arrested after all. She was thrown out of the restaurant.

There is a lawsuit, according to the article, and Michigan does have LGBT protection:

How many GGs have had to use the men's room at some stage or other

I have but only a few times, when the lines were so long for the ladies rooms, there wouldn't have been enough time during intermission. I peeked in the door first and saw no one in the men's, and so I went. Other women followed me.

I don't think that any man walking in behind us would have felt threatened though. Just as I don't think that the majority of GGs would feel threatened by someone who is transitioning. Of course I don't know everyone who is transitioning, but the people that I do know and the pictures that I do see do not look like the mind's eye image that a lot of people have, when they think of "predators wearing dresses".
