Technically, there are racists of all stripes. My parents were racists in their use of language and Republicans at a time when their party and they supported the Civil Rights Movement. I used racist language right up to the time I bought my first Bob Dylan album, in 1964. Harry Truman, in "Plain Speaking," admitted to using the "N-Word," on occasion because "old habits are hard to break." The President who unilaterally desegregated the Armed Forces and risked losing the 1948 election because he included a "Civil Rights," plank in his platform, regularly used the "N-Word."
I say all this to try to bring the discussion to a place above a Junior High School level treatment of racism. Racism in the Democratic Party was a complex matter. Southern Racists like George Wallace vowed to keep "Segregation forever." Many performers and other artists discriminated against Southern Whites, because their accents were "evidence of racism." In 1965, Lyndon Johnson signed landmark Civil Rights bills into law and the Southern Democrats left the Democratic Party in large numbers. But, many in the Democratic Party still equated "White Southerner," with "Racist." That discrimination, as I note in my meme made many of them ripe for recruitment into the MAGA movement.
