Jason Sperber has some thoughts worth considering about when Halloween costumes are offensive and worth avoiding. Jason and I weren't close friends ourselves, but we had several friends in common during college, and we often sat at the same table in the dining hall. I don't think either one of us expected to have much if any contact with each other after we graduated, but I recently discovered that he's blogging in several locations, mostly in the context of race, and I found enough of it intriguing to add his blogs to my RSS reader. I've put up links some of the places he blogs in the sidebar, but I've been waiting for a post by him that I wanted to say something about so I could mention him in a post.
I think a lot of people who claim certain kinds of costumes to be offensive do an absolutely awful job of explaining why, and those who don't understand the reasons usually just write them off as being too over-sensitive. Sometimes maybe people can be over-sensitive and get offended at something they shouldn't. Other times maybe there is cause for offense, but it's not a grave enough concern to justify the kind of outrage you sometimes see, and besides there might be more productive ways to address such issues than complaining about one's rights being violated simply because one has been offended. Still, there are good reasons to avoid certain kinds of Halloween costumes, and Jason provides some good explanations (taken from tolerance.org) for why it might be bad to use a variety of different kinds of costumes. The reasons vary in kind and in degree of importance. I want to try to make the moral reasoning more explicit, since some of them go a little too quickly for my philosophically-trained ethical thought processes.
