But if you're arguing that the flag means racism because of the civil war then you have to think of the racism that followed the civil war up to mere years ago. Really, you could argue that the current US flag represents racism, just like you could for other country's flags.
General consensus is that the civil war was fought over slavery though, as far as I understand it (GCSE level) it was fought over slavery more so than other things.
Originally it was never about slavery. It was more about the Union getting back the troublesome deserters. Then the Union realized "oh shit, the confederacy support slavery made cotton, and was one of the biggest exporters of such cotton to the British (who had at the time abolished slavery [EDIT] in 1833). That means that its only a matter of time before Britain decides to throw its weight in the form of troops, boats, etc." because, I guess Britain wasnt above getting goods made from slave labor even though they didnt use slavery anymore or something like that.
Then lincoln looked at this and was like, "wait a minute! if we can villianize the south and say this is a war against slavery, Britain will lose all respect in the world's view, mainly cause they're hypocrizing." But the problem with that was, there was the boarder states to think about (Maryland, Missouri, [later] West Virginia, and Kentucky) who still enjoyed slavery. The real issue was mostly Maryland, cause then you'd have washington DC flanked on the north/east by confederate supporting Maryland and west/south by Virgina (which is VERY bad to have your capital like that).
So then Lincoln made the Emancipation Proclimation came around, which stated (paraphrasized) Slavery is now illegal in all territories of rebellion against the Union. However, the clause of that was slavery was still legal IN the union.
So it told slaves, "hey, run to the north, you wont have to break your back in the field picking cotton, and we can cripple the south and win your freedom." Then once they crossed intot he north, they were drafted or put back into slavery in the north, and their "saviors" just sorta shrugged and were like "what? Oh, didnt you read the fine print?"
And there were in fact Slves that fought for the south out of freewill (I know, the irony of that statement) cause they liked the way of life better. I mean, there were black plantation owners and slave holders.
So yeah, the who slavery thing was an afterthought. First and foremost, it was keep Britain the f--k out of this as much as possible (since the Union was staring down blockades and having their merchant ships raided by English Privateers. And that solely depended on keeping the south from winning a major battle (Antietam/Gettysburg) and making the war about freeing the slaves and making it look like a major country that had abolished slavery would be supporting it. Thats why for my college history final paper I wrote about how Antietam was the real turning point, and not Gettysburg, because it pretty much promised that Britain couldnt get into the war without taking major flak from other "free" nations and let Lincoln give his pre Emancipation Proclamation speech.
