No, I'm saying there is no evidence for a Nixon SS, and you haven't provided any.
"One of the pressing issues of Nixon’s first administration was school desegregation. Despite the unanimous ruling in Brown v. Board of Education Topeka (1954) and the passage of the 1964 Civil Rights Bill, 80 percent of schools remained segregated throughout the nation’s South.
In 1969, in another unanimous decision, the Supreme Court decided in Alexander v. Holmes County, “to terminate dual school systems at once and to operate now and hereafter unitary schools.”
The plan proved pivotal to the end of school segregation.
In fall 1969, 600,000 blacks attended desegregated schools in the South; one year later 3 million had been integrated. By percentage in 1968, nearly 70 percent of black children were segregated from their white peers; by the end of Nixon’s first term it was just 8 percent.
Extending Civil Rights and Equality of Opportunity
President Nixon signed the Voting Rights Act of 1970, nationalizing the 1965 legislation and expanding its reach to northern states.
The Nixon administration ended discrimination in companies and labor unions that received federal contracts, and set guidelines and goals for affirmative action hiring for African Americans."
