That's nice of you to believe that, but it doesn't make it true. Or the right thing to do. Thomas Jefferson was a Deist, not a Theist. "In God We Trust" and "under God" are relatively new additions to US mottos and the pledge. I can agree that this country had a lot of Christianity absorbed into the founding documents, but it was not the basis. I don't see Christ mentioned at all, and the only references to a deity were the seemingly unChristian terms "Nature's God" and "Creator".
That also isn't necessarily true.

The majority also used to dictate that Blacks didn't have the same civil rights as whites. Majority rule can also be mob rule, and that's not an American ideal.
