Going back to at least 1955, with the establishment of the Weekly Standard, with the first Op-Ed proudly proclaiming "Conservatism stands athwart history, Yelling STOP!" just months after the Supreme Court ended segregation with Brown v. Board of Education.

Conservatives wanted to stop desegregation.

Then in 1957, Buckley wrote this in The Weekly Standard:

What kind of circumstances do we speak about? Again, let us speak frankly. The South does not want to deprive the Negro of a vote for the sake of depriving him of the vote. Political scientists assert that minorities do not vote as a unit. Women do not vote as a bloc, they contend; nor do Jews, or Catholics, or laborers, or nudists-nor do Negroes; nor will the enfranchised Negroes of the South. If that is true, the South will not hinder the Negro from voting-why should it, if the Negro vote, like the women's, merely swells the volume, but does not affect the ratio, of the vote? In some parts of the South, the White community merely intends to prevail-that is all. It means to prevail on any issue on which there is corporate disagreement between Negro and White. The White community will take whatever measures are necessary to make certain that it has its way.

So fascism, hatred, bigotry, stealing elections, racism, homophobia, misogyny....these have been at the heart of Conservatism, and anyone who thinks they haven't been is deluding themselves.
