I don't get it. I mean, you don't see black people wearing whiteface when they dress-up as white characters, and frankly the only time I see anyone wearing white face-paint to some degree is they are dressed-up as the Joker (which lots of races do, and that isn't whiteface so much as a dab of stark-white paint). Yet, a chunk of white folk either dress-up as black characters and apply blackface ignorantly at best, or maliciously at worst (e.g. not just blackface, but trying to look extremely stereotypical like the, "Sambo," cliche or such). I will admit sometimes people overreact to something and think it is reminescent of blackface when it is not--e.g. the recent controversy over Katy Perry's shoe-line that doesn't look like blackface so much as really ugly shoes. That said, for every time people are maybe being overly sensitive, there are 100 occurrences of actual blackface or blackface-related imagery that are stupid and offensive. Everyone, please just stop engaging in blackface, you'll only look like a fool.
