It's amazing what superstition can do.
This is kinda like the spreading of AIDS in Africa. An infected male sits down with the local witch doctor and the witch doctor tells him the way to cure it is to have sex with a virgin. So the idiot runs out, rapes a 12 year old girl, and thinks he's cured when all he's done is infect more people and doomed an innocent to death.
Cultural stupidity and superstition can do more harm than good.
South Korea wants to put and end to this, it's going to be like the War on Drugs here. Millions wasted trying to "fight" it on the street level with dealers and users when they need to put more time in overcoming ages old stupidity.
