Redhead 12-year-old assaulted over Facebook message citing South Park episode?

LA County detectives are investigating an assault on on a 12-year-old boy which may have been incited by a Facebook group message referencing a 2005 South Park episode. “The boy was kicked and hit in two separate incidents (…) by as many as 14 of his classmates.” The attack followed a Facebook message promoting that date as Kick a Ginger Day.” Sadly, not the first time for such stupidity.
