I do know about the "Southern Strategy" lie. It is not a true.

There are three aspects to the Southern Strategy. First it is alleged that Barry Goldwater’s vote against the 1964 Civil Rights Act proved he was a racist and his appeal to “states rights” implied a continuation of Jim Crow. The reality of Goldwater’s alleged “racism” is much different, however. Goldwater had been instrumental in the effort to integrate the Arizona National Guard even before Truman integrated the Armed Forces. Goldwater had voted for all previous civil rights legislation. He was only opposed to two provisions in the ’64 Civil Rights Act; provisions which affected private property. He believed that private businesses and clubs were subject only to market forces, not government mandates.
The second aspect alleges that Richard Nixon used hidden code words that appealed to racists within the Democrat party and throughout the South in an effort to win white votes by exploiting racial tensions. The problem with this line of thinking is that, in order for racism to be hidden inside another viewpoint, that second view – to be a useful hiding place – must be one that can be held for entirely legitimate reasons. In other words, these are also positions principled non-racists can hold. The views are racist simply because they are defined as racist, a tautology.
The third aspect for establishing the Southern Strategy myth was laid with another falsehood; that all the former Dixiecrats had joined the Republican Party after Nixon allegedly used the used the Southern Strategy. The Dixiecrat Party was a third party that splintered from the Democrats because of their dissatisfaction with Harry Truman over the civil rights issue during the 1940s. The goal of the Dixiecrat Party was to continue segregation and white supremacy in the southern states. Senator Strom Thurmond left the Democrats and became their presidential nominee in 1948. After losing the election, Thurmond returned to the Democrat Party, but later switched to the Republicans in 1964. However, almost all the other former Dixiecrats remained in the Democrat Party until they either retired or died. Fulbright, Wallace, Gore and Byrd retired as Democrats.
