The only way I see any kind of healing after this is if fraud on a massive scale is proved in a court of law and Trump is declared the victor before the deadline is reached and the House has to decide.

At that point I think media might actually report on the court cases simply because they realize that civil war is inevitable if they don't, and that would actually hurt their bottom line.

If the fraud remains unproven, if the courts side with Biden despite whatever proof is available or if either Biden or Trump is declared the victor through a vote in the House, then I think you're entirely fucked. The two sides will never, ever reconcile without first going through armed conflict.
