Ms. Narrow Minded (rebelfighter) meet Ms. Judgmental (Tiki). Dear god, "Inappropriate Behavior" is one of the tools used by the DarkLords to control us and have us judged by one another to keep us in line.
I've got an antidote for that: Don't look. Keep your eyes - and your narrow mindedness - to yourselves. Such unpleasant little minded people.
Like Chook said, in many areas of the world it is common for people to arrive at public beaches, strip naked and put their swim suits on. Or not. I've been to beaches in Europe, the Caribbean where this occurs routinely and women without their tops is no big deal. Unless it was my ex-GF (and yes they were real. Expensive).
