I've been visiting and living in England since the mid-1970s. I love it but am disgusted by the ill-mannered and ill-educated responses to our Constitution and our country. What goes around comes around.
The reaction is one of anger and frustration, not hate for America.
Most British people like the US, and many people here are fed up of these spree killings. And children as victims just fuels more anger. And many Brits will never grasp the gun love in the US. I do, but guns have never been anywhere near as mass owned as your nation. We were built on the sword, not the gun. And we kill with knives, not guns.
