Is the United States becoming more secular?

According to Ellen Johnson, president of American Atheists, more people are abandoning organized religion. I guess what I’m asking is atheism really growing in America according to your own opinion? Do you think the majority of people who are abandoning their default religions are really turning to atheism or are more former religionists turning to deism, agnosticism or spirituality (without religious dogma).

I want to keep the answers to where we think America is heading in the near or distant future and why you think so. This is not a debate about theism vs atheism. Here is a video from Fox News with Ellen Johnson debating several other people on this issue. It’s about a little under 8 minutes long. I struggled on deciding whether to put this question in general or social since it is somewhat of varied question but I didn’t want it to veer off topic. http://www.atheistnation.net/video/?video/00911/atheist/growing-atheist-movement-in-america/
