Now, for an example you said that Black Americans' interests were largely aligned until 1965. I think this is an oversimplification, but to go along with it, why do you think that would be the case that they were ever aligned? Was it, perhaps, because there was some law or group of laws that identified them and affected them as a group? Could it be they came to realize this, and then sought to advance their interests in solidarity, as a result of experiencing the injustice that affected them specially?
