It’s liberating. Be weird in public!

That's the problem. It isn't always clear to all people exactly what causes harm to others. For example, it is generally agreed upon that exposing your "nether region" is harmful to others even though all you are really doing is giving something for others to look at. Maybe some of the other weird things they see could be equally harmful? If your weird behaviour is commonly weird then you might have some precedent to look upon, but there is no way to tell what is and isn't harmful to others until it has already happened when you are being uniquely weird.
