You know how you learn?
You learn from making mistakes. For instance, those that voted for rump in 2016 really should have learned from those results not to vote for him again.
Well, we maintain museums reflective of our past to teach people what happened and to spark discussions about how it happened, and how to avoid it happening again. Sometimes museums show progress and seek to inspire the newest generation to strive for positivity, to expand creativity, and to uplift people in general.
Donald rump is effing with our showcases in every way. Who does he think he is? And, I'm telling ya, the majority of the US population hate his guts! He cannot diminish any of the ugly truths that we have learned from. Slavery did happen. The Holocaust did happen. There was a Trail of Tears. And, one day, there may be a rump museum showing how he rose to power, what awful, vicious things he did to people, and how we overthrew his regime and freed ourselves to once again succeed in our daily lives. He won't be able to change those facts, either. We are learning how to protect ourselves. I hope he's alive, in jail forever, to know about such a museum. It is the best revenge.
