One of the shirts we have available through Christian Books and Things (http://www.whiteheritagestore.net/) is the tee-shirt Klan Kids Kare. It always amazing to me that some people want a bogey man to hate. They think they are the only ones filled with the love of Jesus. "How dare those nasty Klansmen talk about love and talk about Jesus."
Anyway you might want to check out their article here: http://220.127.116.11/search?q=cache:1zb37qomeSEJ:www.ibabuzz.com/aparentlyspeaking/2009/06/01/ku-klux-klan-t-shirts-for-kids/+Klan+shirts&cd=4&hl=en&ct=clnk&gl=us
When you go to the link you will see a comment by a Joseph Bernarsky claiming to be an ex national leader of the Klan. Who is the heck is he? I've never heard of him before!
