Last month we reported on National Kick a Ginger Day, promoted via popular social networking site, Facebook.
This month we have discovered the proliferation of support for Hug a Ginger Day, a direct response to last month's South Park influenced attack against red heads.
December 19th 2008 has been earmarked for the day. The Hug a Ginger Day Facebook event currently has 160,672 confirmed attendees at the time of writing.
Update: It seems the event has now been removed.
