Just happened that 'ol Trayvon won the 'lead lottery' a bit sooner than many others...
I say to those that like to call themselves "Nigga" or "Nigger", we should oblige them and call ALL people of color "Nigger" and follow that up with an explanation that "some of your own refer to themselves in this manner, so we are going to refer to ALL of you in this manner until "YOU" make it perfectly clear that the NIGGER word in not acceptable by "anyone" and that blacks are not given an exception. Then and only then will we be able to be more civil and just call you "Sir", "Mr", "Mrs", etc. like we would all prefer. (Well - some white boys need a little beat down in that regard).
