The costumes shown in the campaign are more an issue of taste rather than race. The arab suicide bomber is in pretty poor taste but there is nothing racist about dressing up as an arab. In the past I've used an arab costume, the decision was not inspired by any notion of race, but simply another costume to go with the myriad of other costumes that night. Equally on another night I've been a bee (yeah that was a good night), I wouldn't say by dressing up as a bee I'm trying to mock bees. I'm not beeist (a word I will now use everyday).
