The
United States has now 'banned' the Confederate flag and Confederate statues after almost 150 years. Americans don't like to be reminded of slavery or the Ku Klux Klan.
Germany has banned the Swastika and the SS symbol since the 1950s. They don't want to be reminded of Hitler, concentration camps, and WWII. Both countries accept the symbols in the contexts of art and sometimes teaching.
Like that part of history never happened. The new Politically Correct (PC) way of rewriting history. Take out anything offensive. How can anyone (young) truly come to their own opinion about an issue when history gets partly 'sterilized'? How to learn from the evils and mistakes of the past?
