whatever happened to peace?

Sitting in the backseat of the car. We're traveling home for our annual pilgrimage to Illinois, my youngest son is in the driver's seat this shift. As I sit here, I scroll through Facebook and am assaulted with images of ministers I went to school with and their guns, their wives in NRA t-shirts carrying NRA mugs. 

Memes talking about the second amendment rights everywhere, and "liked" by others I used to think I knew. 

Whatever happened to Jesus being the Prince of peace? Whatever happened to laying down our swords and carrying the cross of Christ?  

What has happened to Christianity? I don't recognize this form. I hate it. I am saddened by it. And it does noting but push me further away from them.
