The Confederate flag is representative of history- be it good or bad. Can't erase U.S. history. Shouldn't be erased either. 

We learn from factual (the Confederate States of America consisted of the governments of 11 Southern states that seceded from the Union ...Convinced that their way of life, based on slavery, was irretrievably threatened by the election of President Abraham Lincoln) history.

 Why would anyone disapprove of that? 

PS this is *especially important if anyone feels 'threatened' by the election of our seated President Trump!
