I would say yes, so long as the costume wearer does not engage in threatening behavior toward other revelers.  It&#x27;s offensive and in poor taste, but I think people have the right to wear stupid things, even offensive things.<p>They can wear nun&#x27;s dresses or vicar&#x27;s clothes with very inappropriate insinuations, etc. (given the &quot;misconduct&quot; of priests, etc.)<p>Or banning Nazi, Ghadaffi, Kone, BinLaden, etc. costumes, they are in poor taste, but I don&#x27;t see the merit in banning them outright.  Or doing untoward things to the effigies of unpopular politicians.<p>It&#x27;s my opinion, and I imagine others would be offended, and I might be offended by some costumes, maybe even feel uneasy about them, but I still would say people have the right to express themselves, so long as they don&#x27;t engage in threatening behavior.  Some (political) expression will feel very uncomfortable, but that&#x27;s necessary to have in a free-ish society.
