Lol. Historically, yes the Democratic party was the party of the KKK, that could be tied more to Dixiecrats (Southern Democrats from Confederate States than the entire party itself. Republicans like to try and make up that Democrats didn't support the Civil Rights Act of 1964, but if you were to remove the Dixiecrats from the equation- they were the alt right of their day- then the Democrats did vote overwhelmingly in favor of the Civil Rights Act of 1964.
The Republicans then used the Civil Rights Act of 1964 to appeal to Southern whites who were concerned that blacks were gaining to much in society that became known as the Southern Strategy and helped get Nixon elected and almost permanently turned the deep south red. The GOP admitted and apologized for doing this to black leaders in 2004 while also trying to get black people to vote for them to reelect W. Bush, he ended up winning on 5% of the black vote.
The right has used iden y politics to appeal to white voters for generations and is one of the primary reasons why black voters have become permanently alienated from the party and why Hispanics and Asian American voters have mostly stayed away too. Believing that black people have been "brainwashed" into not voting Republican is yet another reason why black people often vote against the GOP, not to mention the GOP frequently votes against things that African Americans value on both the state and national levels and are almost always on the opposite side of issues that they care about; i.e, police reform, & health care.
Trump had a long history of racism, decades worth of stories and accusations; not just against black people (twice being sued for housing discrimination against black people post civil rights era) but against Native Americans, Latino's and Jewish people. You can't ignore 30 years of history just to make a point that isn't remotely accurate
