IIRC, the Supreme Court or one of those high courts already ruled not long ago that it is unconstitutional to stop natal women from going topless in public if it is a protest. If they do rewrite the law to stop "men with breasts" from going topless in public, I'm pretty sure they can still do it as a protest. Basically, all you have to do if they try to arrest you is say it's a protest of something or other. Whatever. Maybe they'll still arrest you, but then you get all rich and stuff, eventually.
