How do I stop my 12-year-old daughter from crying herself to sleep? I have punished her and she still does it.

To slaves: “You can forget your notions of freedom. We voted fair and square and your side lost.”

To blacks: “You can’t drink from that water fountain… eat in this cafeteria… ride this bus… go to this school. We voted fair and square and your side lost.

[with republicanism being the rights-protecting form of governance afforded us by our Constitution]

What are "demonic attacks" and how can one tell when they're happening to them, or someone else? How would one go about dealing with it?
