The video is shocking not just for its content but for the glee the family seem to show regarding the content. This isn't their first rodeo with racism. They're dyed in the wool, routine racists using slurs that are everyday language to them. That's what I take from it. As far as the sedative goes, if she did take a sedative, then all it did was loosen her tongue and bring out her inner racist. In vino veritas, goes the old Latin saying. Wine brings out the truth. So does whatever pill she took.
