How did the Civil Rights Act of 1866 become law?

Are you referring to the Civil Rghts Act of 1964? There was a Civil Rights Act passed in the early 1870s, during Reconstruction, following the U.S. Civil War, but it has received little popular attention.

The Thirteenth Amendment to the U.S. Constitution was proposed in 1865-1866 and effectively completed the abolition of slavery in the U.S. The Fourteenth Amendment followed in 1866 and defined African-Americans as U.S. Citizens (thus superceding the Dred Scott decision).

If Democrats were opposed to Civil Rights, then it's unlikely that virtually every minority would support them. The fact is that at the presidential level, Democrats have led the way since at least the early 20th century. FDR allowed blacks in the military, Truman desegregated the military, JFK/LBJ introduced Civil Rights and Voting rights legislation, and Democrats today are on the forefront of gay rights. Where you're confused is by the Dixiecrats. These racist Democrats were wooed and courted by Republicans starting with Nixon, but especially with Ronald Reagan, who famously launched his presidential campaign in Philadelphia, MS, known only as a place where 3 civil rights workers were murdered, and there he spoke about states rights, which was a code word for segregation. The Republicans successfully attracted the racists into their ranks, and now the Democratic Party appears to have a lock on almost all minorities. After all, minorities know it's the federal government, not the state governments, that have protected their rights. Your revisionist history should embarrass you. If you knew anything about history, you would know that blacks were Republicans early on simply because whites in the south were Democrats and those Democrats were racist. But, it's more than 40 years since the brave JFK/LBJ administrations all but threw out their trash and the Republicans lapped it up. The fact is the Republican Party is the white party, and it's candidates, like Rand Paul, want to legalize racism (by allowing businesses to discriminate), oppose gay equality, cut programs that helped overcome the legacy of racial discrimination, opposed laws to protect a woman's right over her own body, opposed laws to protect women from some forms of discrimination, and so on. Why do you think you know more about racism than the victims of racism, who by a very large margin support Democrats? By cherry-picking history and looking back to an era when the Republicans had a chance to be a mutlicultural party, you are fooling no one, but instead exposing your own ignorance, an ignorance that is destroying (thank God) the Republican Party.

That was the 1950's (Martin Luther King!!!!!!)
