It exists today: The Tea Party + white supremacist groups
The CofCC has openly admitted to organizing and attending Tea Party rallies and the are the largest white supremacy group even larger than the KKK with 15,000 members. They are the suit and tie racists that have the money and power to be government leaders, military leaders, corporate heads, and in law enforcement.
The CofCC is the brains of the white supremacy movement and produces CCC video used by the Tea Party and groups like pushbacknow .com. They have their own radio and internet broadcast stations and are more subtle and deceptive in getting people to believe their views usually playing on patriotism.
This makes this movie even more relevant today in that groups that advocate such hate are more deceptive and cryptic in getting their messages out!
