"Try telling them that the KKK did not use the ANV flag until after World War 2."

Uh actually it was this one.

The battle flag of the army of Teneessee.

But it dose help to know that they didn't use it until after WW2 that will help out with my position a lot.
Would you say that it would be ok for me to call it "St. Andrew's Cross" and how would I defend the flag better?

What else could you tell me about the CBF?
