For whatever it's worth when Dance in a Vampire Bund came out on DVD in France I was shopping at a
fnac store which is really mainstream,the anime part of the store was showing DIVB on TV screen and that scene in question came on, I asked someone working at the store if costumers ever complained and nope,though apparently some costumers were just bewildered at the idea of the scene being a turn on for some but they weren't outraged or anything.
