It's difficult to be more racist and bigoted than this...

Something for my new WTF department: EFLGeek.com has some shocking pictures of some placards with some very provocative and racist language right here in Korea. Yes...I know...its difficult to fathom but they must be seen to be believed. Simply outrageous and offensive to say the least.
I can't help but wonder if the people who placed these signs have any possiblity of being sued by the people whose names (first and last!!) have been made public in such a way. Would the Korean high court be inclined to recognize the linguistic and cultural implications of the language used and would they be able to apply the slander/libel laws when the source of the slander is not Korean?
