I disagree with the end statement. I don't buy into the idea that Christianity is about the end state. There are segments of Christianity that are focued on that. And that is problematic in many ways. The whole Rapture theology is all about the end. It creates real life problems - it's why we have an entire segment of Christianity that disregards stewardship of the planet. I don't think it's fair to say that all of Christianity sees things this way.
When I look at Christ's teachings he's talking about the kingdom of God in our midst - right now and right here. He's talking about how we live right now. It's always about God coming to creation, rather than humanity escaping creation to reach some kind of goal.
I think the issue is that so much of American Christianity has done what Americans have always done - taking something that wasn't theirs, kicked out the original, and then reshaped it to meet their needs. American Christianity worships America more often than not. It took the name of Jesus, kicked Jesus out, and then remade him into some some nice white guy with beautiful hair who doesn't upset the apple cart.
I don't like Christianity that is focused on the end state for a variety of reasons. If that's all Christianity is, then its a rejection of what Jesus is about and what he calls on followers to be. It makes Christianity into nothing more than any other empire that teaches that the ends justify the means, that the strong survive, and that might makes right. These are segments of Christianity for sure, but I don't think they are any different than so many other things. They just label it Christianity.
