OK, so, here's my stance.
The current media hubub over the confederate flag, is all about a flag that did NOT exist historically and was created in the 20th century by combining 2 flags that did exist during the civil war era. The flag we see today is an amalgam of the "battle flag" of the confederate (which would have been a square piece of cloth, not rectangular at all) and the confederate's 2nd naval jack. This flag came to creation almost 100 years after the civil war ended and was created so that extremist groups could inform others that their belief about race reflected that of the 'old south'
In the end, the decision to remove the flag was Disney's prerogative. They WERE using a historically accurate flag known as the "blood stained banner" which is why I think this has become a hot button issue because its the first historically accurate flag to be removed.
I'm not for a ban of the flag, and persons and businesses are free to choose what to display and sell themselves, BUT no one has forced a singular person other than a government entity to remove the flag. However, on that note, if there were someone who truly told me that they wanted to fly a confederate flag because of "southern pride" or "historical remembrance" I would neatly insist that they use an accurate flag.
As for the subject of other flag removal because of PC issues, no other country is using an out-dated 'defeated' model. I'm certain that if some of those descendants of Japanese Americans were to walk in and see the 'rising sun' flag, they would be offended. Much the same to any descendants of Holocaust survivors on a Nazi flag. The simple fact is, however, neither of those countries at Epcot display the flags that were used historically during those horrible things.
And when it comes to 'removing presidents from money' That is no where near the same thing. The movement is to replace 1 or 2 presidents with women who contributed greatly to society. Its a movement for equal representation, not oppression because they did something bad in the past.
ONTOP of that, to anyone complaining about the swastika, yes, this is exactly the same. An extremist group (nazis, racists) took an item with real historical significance, (a real swastika is a Buddhist symbol for peace but it looks different. the real confederate flag meant something, but the way it looks was changed) and changed it to be something intended for hate and hoped that people would never look to history to find the truth.
