First of all, let me ask you, people who paint your face black: has a person of color ever stopped you and thanked you for your use of blackface or "black face" as you put it (ed note: wtf?)?
Because maybe that should be your first indication that it is, in fact, not a compliment. It is actually racist. Somebody has made a handy flow chart for those of you who are having trouble keeping up on this subject. You might want to print it out and keep it handy for the rest of the month. Maybe show it to your friends who didn't get the memo.
Whatever you do, just please, PLEASE, for the love of all things NOT RACIST, STOP IT. Just stop it.
