President Obama January 16, 2014: "...Today, America embraces people of all faiths and of no faith. We are Christians and Jews, Muslims and Hindus, Buddhists and Sikhs, atheists and agnostics..."

In the past (including his 1st inauguration address and last year's Proclamation of Relgious Freedom), he has only mentioned "nonbelievers". This is the first presidential reference to acceptance of "atheists" and "agnostics".

How come we don't get capitalized? but, hey, we're making progress...
