Not just christianity its all 3 of the abrahamic religions.
Just spreading backwards middleeastern ideals
I've noticed that Judaism, Religion 1.0, has 15 million Jews but half of them are cultural Jews, peaceful, prosperous and calm . Jews do well in America, in California in particular, in Hollywood and Israel aside, they seem quite nice. Then there is Religion 2.0, Christianity, also doing well in America, apart from the odd abortion clinic bombing and the Creationism school syllabus fiasco, but doing ok, not angry, just simmering, keeping the kettle hot.

. And now we have Religion 3.0, it's the latest release, wink wink, Islam. Just starting out in America. Not doing too well. Been some issues with planes flying into buildings and shootings and the occasional beheadings and numerous failed terrorist plots, kinda boiling over, not settled, a little annoyed.
Now that we have accumulated all 3 Abrahamic religions in one giant melting pot, where do we go from here? America is waking up to a period I'm sure history will reflect on, of atheism. Polls show, that the largest growing minority are atheists, but they don't have a voice YET. So, in one place on Earth we have the 3 Abrahamic faiths living side by side with atheists all checking out the water slides and the Casino's, and I wonder where this will lead America as it evolves and information, FACTS, reason, science and faiths, what will be the outcome? Because when the dust settles way off in the future, it could be that America's chief export to the world will be knowledge, not democracy. And I find that interesting because as global amassed information permeates around the world, people will naturally gravitate toward it. Knowledge and it's technologies that spring forth from it raises the playing field for everyone and as we all become more connected via trade and sport and politics, we amalgamate, we condense and our differences start to disappear. We are heading forward toward a global family. Europe is condensing, as will the Middle East, China, India, Brazil, all working toward less barriers and more opportunity's for trade and culture.
A few hundred years ahead, if we haven't destroyed our green planet, we might find our selves living as a global community without borders where the currency of prosperity is knowledge, shared globally for the benefit of everyone and the enrichment of a unified planet Earth.
