john adkisson:

Polls show that between 10 and 20 percent of Americans are devout non-believers. And there is zero correlation between faith in a supreme being, and morality.

That's a nice sentiment, but ultimately you're imposing what is moralin your eyes onto everyone else - which is essentially what you're accusing Warren of doing.

The "Greatest" commandments of the New Testament go as such (paraphrased):

1. Love God
2. Love everyone else.

By my reading of the Bible, I happen to arrive at essentially the same conclusions you do. But, for Evangelicals or other Augustinian types, you cannot be (fully) moral if you don't love God, so to demand that they should accept non-Christians under their moral code is as though they are demanding you to accept their opposition to same-sex marriage and abortion as in line with your own.
