Racist Flags

This is the flag the Klu Klux Klan flies (alongside the Stars-N-Stripes most often).

This is the Confederate Navy Jack.  I'd have shown the battle flag of the Army of Northern Virginia, but its square form is less commonly depicted as a "Confederate Flag".

One was created by racists to fly and promote racism.

Which one is more recognizable?

The Confederate flag is used more and is seen more because while some will use it for racism and some see it as racist, it was made to symbolize other things besides racism.

The KKK Flag has never represented anything but, and you just never see it openly flown unless there's real strength in numbers protecting the Klansmen from violence.

I consider that the Klan flag is rare a sign that racism really did die in this nation a long time ago.
