I just had a thought, are there any similarities between Kathy Griffin’s apology for a mock beheading of Trump, and other public apologies from the right side of the isle (just reflect on what happened before the election with Trump and his treatment of women)?
Do we have a problem with public apologies as a culture (maybe as human beings), rather than just partisan problem? Do we have a problem with apologies that are designed more for PR and damage control than honestly accepting responsibility for bad behavior? Do we as Americans have problems blaming others for our transgressions rather than owning them without qualification?
What would it look like to say: I was wrong, there is no excuse for that. No one else is to blame for my choices but me. I am sorry for the damage I have caused and apologize to those I hurt. I am going to do what I can to make amends, and I accept the consequences.
This is really, really, hard. But I think anything less hurts everyone involved. When we are more concerned with saving face, than owning the truth we perpetuate the problem.
This is a hot topic, just google the issue of organizations, governments, law enforcement, or doctors apologizing and you will see that we have a big problem.

For a culture who is pure spectacle and entertainment, the surface is all of life, and where it is lived. For, there is no deep character and interior life. To save face, is to save our very lives.
We can contrast our culture, with a Biblical culture, where repentance was a sign of an interior life and soul in a complicated life that needed forgiveness from God and man.
Well said!
