LL Cool J lost any cool points he might have had remaining when he apologized to the South for Sherman's March to the Sea in a Confederate-apologist song, and compared wearing do-rags to wearing the Confederate flag as if they were on the same level.
I was unaware of that. The extent of my knowledge is that there is a well-known musician/actor who uses the stage name "LL Cool J." That and what he looks like, but not much else.
