Who cares? That doesn't really mean anything. I am the GG Grandson of a CSA officer. It's not as if the southern / Confederate states invented slavery and racism. The black codes in the north were so restrictive it is hypocritical to paint the south as evil and racist as if the north was some great utopia of progress. Of course Illinois no longer had slavery as it was not an agrarian state though also had laws on the books that blacks (free or otherwise) could not become citizens of the State.. that is a pretty convenient out.
The anti-Confederate flag, monuments, etc. is mis-direction and the BLM / social justice woke cancel culture warriors just lashing out at something, anything, as they can't rely on actual facts and statistics to drive their myth / lies of systemic and institutional racism, inequality, etc., etc., etc. For the exact same reasons anyone is offended by the battle flag, Sully statue, etc. they should be offended by the U.S. flag, the Texas flag, the England flag, the French flag, Lincoln statues, just about anything having to do with any white person pre-1900.
Are there racist people today? Sure. Are there homophobic, anti-semite, bigoted people? Sure. They are minimal and you cannot outlaw feelings and beliefs with legislation. The reality is there is no systematic racism, there are more poor non-black people than black but the non-black don't commit the majority of violent crime. There is no lack of justice for victims of bad-cops.
You can bring down or ban all the flags you want, tear down all the statues you want, proclaim all the pancake syrup and rice packaging to be racist that you want.. and it will change exactly NOTHING. History won't change. Maybe a few laws will change, some funding will change, more useless legislation will be passed, but none of that will matter.
Once Kellen and those in the rabble are out in the real world they will realize that the only thing 99.9999% of the people care about is what type of person you are, good or bad, if you are educated or skilled enough to do the job, can you set goals and achieve them, do you take individual responsibility, are you moral, etc., etc., etc. People are interested in your character, not your color.
So called social justice warriors are just spreading Ignorance, intolerance and hate more than those they accuse of the same.
