If I understand the oral arguments in Merrill v. Milligan, the state of Alabama wants to use the 14th Amendment against civil rights legislation. This is likely, then, Plessey 2.0. We are entering a second era of legal segregation once the SCOTUS says AL is right about the 14th. The Supreme Court is being asked whether the 14th Amendment bars race as a deciding factor when considering racially harmful outcomes. In other words, can Back voters fight back when targeted by laws that don't say it targets them while effectively doing so.
