That old switcheroo is a myth, and like most myths there are bits and pieces that are true.
You already know the only way Johnson was able to get the Civil Rights Act passed (keeping them niggers voting democrat for the next 200yrs) was because of the Republican support in congress. Many democrats in congress opposed it.
So what you're saying is that the Southern democrats joined the Republicans who were staunch supporters of black civil rights just because they were mad at LBJ? That makes sense.
Its not that simple, and quite complex.
You also missed a step in your revisionist history lesson. A bunch of democrat congressmen pissed at Johnson and those Democrats who did support civil rights left the democrat party and founded a party known as the Dixiecrats. A couple names you are probably familiar with...Robert Byrd , Strom Thurman, and Jesse helms. After the Dixiecrats went defunct Thurmond and Helms abandoned their racist ideology and joined the Republicans. Byrd and the rest remained racist democrats.
Surprisingly you only touched upon a vital player of the Southern Strategy. Every source on this subject points to Richard Nixon as the one that really got things rolling. He allegedly devised methods the Republican Party used to gain political support in the South by appealing to racist white voters. Which of course is false..
A New York Times article heading:
"For the first time since President Richard M. Nixon's divisive 'Southern strategy' that sent whites to the Republican Party and blacks to the Democrats ..."
Nixon was an avid supporter of black civil rights, yet leftists paint him as pandering to racists.
To borrow from an article by Pat Buchannan:
In 1956, as vice president, Nixon went to Harlem to declare, "America can't afford the cost of segregation." The following year, Nixon got a personal letter from Dr. King thanking him for helping to persuade the Senate to pass the Civil Rights Act of 1957.
Nixon supported the civil rights acts of 1964, 1965 and 1968.
In the 1966 campaign, as related in my new book "The Greatest Comeback: How Richard Nixon Rose From Defeat to Create the New Majority," out July 8, Nixon blasted Dixiecrats "seeking to squeeze the last ounces of political juice out of the rotting fruit of racial injustice."
Nixon called out segregationist candidates in '66 and called on LBJ, Hubert Humphrey and Bobby Kennedy to join him in repudiating them. None did. Hubert, an arm around Lester Maddox, called him a "good Democrat." And so were they all -- good Democrats.
While Adlai chose Sparkman, Nixon chose Spiro Agnew, the first governor south of the Mason Dixon Line to enact an open-housing law.
In Nixon's presidency, the civil rights enforcement budget rose 800 percent. Record numbers of blacks were appointed to federal office. An Office of Minority Business Enterprise was created. SBA loans to minorities soared 1,000 percent. Aid to black colleges doubled.
Nixon won the South not because he agreed with them on civil rights -- he never did -- but because he shared the patriotic values of the South and its antipathy to liberal hypocrisy.
When Johnson left office, 10 percent of Southern schools were desegregated. When Nixon left, the figure was 70 percent.
Richard Nixon desegregated the Southern schools, something you won't learn in today's public schools.
God I wished Trump would have used this info about Nixon when he spoke to black people.
Here is a link for the truth about the Southern Strategy:

And if you don't approve of the source, then perhaps try reading this one...a book written by two northern college professors, so they must be liberals.
The shift from Dem to Republican in the south was due to economic growth.
