If the battle flag is oppressive then so is the US one as it flew when slavery was in the north, it flew over slave ships bringing slaves here, and it certainly flew out west to the Indians who were killed, raped, robbed, and had their lands taken away.
I want both flags flying as all flags have stood for oppression in the minds of some groups
Learn your history. There wasn’t any U.S. flagged ships running slaves. While they came from the eastern Atlantic area, the majority were Portugese, Dutch, and British.
