Here is the real reason they are after the flag. It represents heresy against the state religion. This is from the great Murray Rothbard more than twenty years ago:
The Union was taken, by its Northern worshipers, from a contractual institution that can either be cleaved to or scrapped, and turned into a divinized entity, which must be worshipped, and which must be permanent, unquestioned, all-powerful. There is no heresy greater, nor political theory more pernicious, than sacralizing the secular. But this monstrous process is precisely what happened when Abraham Lincoln and his northern colleagues made a god out of the Union. If the British forces fought for bad King George, the Union armies pillaged and murdered on behalf of this pagan idol, this “Union,” this Moloch that demanded terrible human sacrifice to sustain its power and its glory.
