Would you clarify that statement PapaNew? I don’t condone racism. But to my knowledge, the only race-based right that the states have amended the Constitution to expressly protect is voting rights, evidenced by the 15th Amendment.
Regarding 10th Amendment-protected state power to segregate, please consider this. While I don’t condone segragation any more than I condone racism, not only did the federal lawmakers who drafted the 14th Amendment arguably overlook segregation issues, but corrupt, post FDR era activist justices wrongly established the PC right not to be segregated outside the framework of the Constitution in Brown v. Board of Education imo. And two wrongs don’t make a right.
As originally intended by the ratifiers during the post Civil-War reconstruction era, the 14th Amendment made state segregation unconstitutional as confirmed and explained in the Slaughterhouse cases a few years after the amendment was ratified.
The feds have used the heinous "Incorporation Doctrine" to give themselves power over all of the rights mentioned in the first ten amendments. The first ten amendments are strictly pointed at restricting the federal government and no one else. The 14th Amendment was never intended to change that other than this one narrow area.
The feds have no legitimate constitutional authority to force integration on the state level or to interfere with private parties at all regarding their freedom to choose or "discriminate". In this respect, Brown v. Board of Education was invalid because it overturned the long-held precedent of Slaughterhouse with no constitutional-based explanation.
