I respectfully disagree with this point. We do need to keep knowledge of history armed and ready, specifically because white folks have been trying to rewrite and reframe history. The younger generation is falling victim to a misinformation campaign that is affecting their mindset. Never underestimate the power of ignorance.
Let me give you and example: I entered a conversation at work with a CAC, who I heard talking about how the confederate flag was a signal of pride for southerners, and not a racist thing. I said it seems like he is trying to redefine a flag that is a known symbol for a people who had decided that they would rather leave the united states and start their own country so they could keep black people as slaves to provide them free labor. His eyes lit up, because he was ready for that argument. He said, did you know that most of the people who were soldiers in the confederate army weren't slave owners. They werent fighting for slavery, they were just fighting for the south, to keep their land and families safe. I said 'oh really, so they probably werent even in favor of slavery and racism then, they were just defending their own'? He was like yeah exactly. He was so pleased, because he thought he had dropped part of his one-two combo. Then, he said some blacks were slave owners, and some were in africa selling blacks into slavery, so it's not like slavery is only the fault of the south. Bamn... the second part of his combo. The south will rise again is just about southern pride, about family and about not being ashamed of living in the south.
I asked him where were these non racist non slave owners when the northern armies left the south, and whites started terrorizing blacks, lynching blacks, burning them out of house and home? If those southern whites were not about racism, why was there no one defending their newly freed southern brothers when southern whites were attacking them? You realize that after the slavery was ended in 1865 all of the slaves still weren't free, and it took two more amendments in 1868 and 1870 to give them citizenship and the right to vote. Imagine that, you need a law to make you a citizen, and but you really arent a citizen if you are an adult but can't vote simply because of your race. So they need yet another law to give blacks the right to vote. And once blacks had the right to vote, there were 14 black congressmen, and 2 black senators from the south. Southern whites hated this, they hated losing money and power, and the Klan formed and widespread lynching started. Southern governments started making laws specifically to suppress blacks. Where was the non racist non slave owning south then? When they were passing laws against blacks (blacks who didn't want to sign a long term agreement with their former owner to work the land and give them a piece of their crops or profits) so they could be arrested and forced to work for their former owners , where was the non racist south? It took until the civil rights act of 1960 to take some of the obviously racist laws off the books in the south. 100 years after the civil war, these people in the south, and all southern governments were still holding on to racism so hard that it took a huge movement to force them to change. 100 years later the people who wanted equality were hung, firehosed, beaten, attacked by dogs, all because they were speaking out about freedom from racism. They didn't think that it should be a law that a black has to give up a seat on a bus for a white person to sit down, so they were beaten. How is that not about racism? So how can anyone argue that the south wasn't about racism? All of the evidence, all of the action points to the south being an institutional and complete supporter of racism. That's not even really debatable. So how can you realistically think all of that can be wiped away by you saying the flag doesnt represent what history shows that it did? He was holding on what he wanted to be true, not what was actually true. Sometimes a history lesson is a good thing. If you know what happened you won't let someone make up lies about what happened.
