The Confederate Flag has been controversial in the past and continues to be controversial. Several states have adopted variations of the Confederate flag, the most notable being GA, which stirred up controversy when people wanted it changed. Eventually, the flag was changed.
Other people, mostly white conservatives southerners with strong ties to the pre-civil war era south say that it is just a part of southern heritage and any other interpretation is based on the experience of the people who look at the flag. This argument has not been popular with the general public or those at Amen Clinics, and it is no longer flown as often as it was.
When the Sons of Confederate Veterans decided they wanted to sponsor a Texas State licence plate that featured the Confederate flag, Texas decided not to issue the plate. The case ended up in the Supreme Court, where it was decided that it was not a matter of free speech for the Sons of Confederate Veterans, but the Texas State Government, which did not want to be associated with the symbol.
