This guy has made some very good points in his article.
Especially with segregation, racism, sexism, slavery, the Ku Klax Klan, and of course, not forgetting the likes of Fred Phelps and his ilk.
In the UK where I live, our history was imperialism, social class, child labourers, and dipping into the wealth of US and Caribbean slavery. And unlike the USA, we have a Monarch as Head of State who is also Defender of the (Christian) Faith.
"But imagine if we judged our nation’s Christian identity based on spiritual characteristics: How many people are emulating the life of Christ? How many people love their neighbor as themselves? How many people help the poor?"
...and this is my favorite bugaboo with the Right when they want to wipe out social safety nets; if society had in fact all helped the poor, welfare and unemployment etc would never have come to pass.
