No matter how badly you want to return to the pre civil rights era so that segregation and discrimination are permitted, we aren't going there. 

We are all protected from discrimination based on the characteristics named in both federal and state anti-discrimination laws. That means you can't be discrimated against for being white, for instance, just like you can't discriminate against someone for being black. Is this actually "so confusing" to you? Because it seems very simple to me.
