I have no affiliation with any political party and many of us don;t claim anything. Whichever political party one chooses don't change historical facts that still impact millions of people. Slavery by law was abolished 150 Years ago but you must know about Jim Crow laws, 13th amendment which basically ok'd enslaving black people again through the prison system, mental trauma, civil rights, etc. These are facts and they still have major impact on people's lives. It's hard to know what that's like if that is not your history or heritage as it pertains to the U.S.
As far as statues. Ummm. That's like telling Jews to get over the holocaust. Also tell Jews to get over having Hitler statues posted up if you want to go there. This is why Germany tore those statues down because it represented the inhumane treatment of human beings and a perverted ideology.
You can;t paint all black people the same. Many vote out of ignorance but many are well aware at the same time.
