That doesn't matter for his argument, though.

Sure the Confederate flag used today was the battle flag and not the flag of the union. I don't think people flying the flag really care about that. Flags are symbols and the south attempt at secession did rally under their military effort and flag.

Today the flag means something very different than what it did.

That happens all the time with flags.

But again, none of that matters for OPs argument.
