Yes, the Civil Rights era is over, because people of all races have civil rights. There are some instances where businesses still discriminate on the basis of race, but they are few and far between. Because systemic discrimination on the basis of race is over, so is the Civil Rights era. Race issues still continue, but not in the context of civil rights.
As we stretch our minds we can embrace that civil rights exceeds outside of just race but those who are fight for their civil rights as gay Americans, disabled Americans, and more. Civil Rights Movement scratched the surface and has thus lead to a revolution. The movement provides hope, focus, and understanding to what lies a head and at what cost.
In one sense the civil rights era may be done because some fundamental values have been questioned and some laws have been changed. And yet there is still a lot of work to be done in the area of racial equality. It may be that as new minorities emerge, it has to be said that civil rights work will never end.
