Stop fighting on behalf of a white supremacist genocidal juggernaut. Let's go with your heroes.

Thomas Jefferson - not just a slave owner, a slave breeder and for profit serial rapist. Raped people that he owned as property, took their babies from them, and sold the babies. Kept a very young slave girl in a cave in his bedroom with no windows and only the one door so he could rape her whenever he wanted. He tried to use his political power to end the transatlantic slave trade specifically to increase the price he could charge for slaves that were born on his plantations.

George Washington - order the genocide of indigenous people all over the colonies. Order Sullivan not only to kill every single Indian he saw but also to destroy every single source of food, every orchard, every farm plot, every single way the Indians could eat. Literally called "village destroyer" by the indigenous peoples because he ordered them all killed and burned to the ground.

Abraham Lincoln - famously abolished slavery? Nope. The Emancipation Proclamation only offered freedom to those enslaved peoples of the 11 rebelling states and only if they took up arms against the rebels. Slavery was left intact in the union and up to the states to decide by vote. Lincoln himself is on record stating that he didn't care much whether slavery was legal or not. He just cared about stopping the rebellion. He is also on record saying that blacks and white probably couldn't ever live together and that he thought the slaves should all go back to Africa.

Harry Truman - worked closely with the Vatican in Operation Paperclip to save almost 10k Nazis from suffering the consequences of losing the war. Gave them fake identities, money, safe passage, new lives, jobs, and integrated some of them into the workings of the US empire. He also oversaw the Korean War where the USA bombed the north until there were literally no buildings left and dropped so much napalm that Koreans in the North needed to live in caves because there was nowhere else to protect themselves from a chemical fire that bonded to human flesh and caused one of the most gruesome torturous deaths we know of. Oh. He also is the only human being to ever order the dropping of an atomic bomb. He did it twice, against densely populated cities, and while Japan was literally in the diplomatic process of negotiating a surrender with the US.

FDR - Concentration camps for anyone looking vaguely Japanese, including the state seizure of their property

Also, the US was a literal apartheid state until the 1960s.

I could go on. Every president since Reagan is super easy to expose as drenched in blood.
