College Humor created this fake ad a little while back for Diet Racism—the drink that has all the sweet ignorance of regular racism but with none of the guilt or self-awareness.

It's actually been quite a year for discussions of racism involving brands. Maybe this fake commercial could be a good hiring tool for potential brand or social media managers. If they laugh, maybe they'll be a little less likely to go full-on racist in a tweet.
If they tell you the Irish really were persecuted too, well, there's a red flag.
