How to change a fundie's mind?

A majority of the religious debates that I get in to are usually between evangelical Christians and such. Most of the time, they are completely unwilling to change their mind about their beliefs. Which makes debating the facts and evidence behind their beliefs completely irrelevant to them.

So, what I think would be a better approach is to debate the root of the problem: the individual him/herself. They are usually closed-minded and unlikely to change. Bring this up with them and describe how this may be harmful to others and themselves.

"New Atheist" movement

I just read this article online talking about new atheism clubs being started in high schools across the country and got to thinking why this is. A majority of new atheists in this movement are primarily in the 18-25 range of age. This is the age of college students and primarily, those individuals moving out of their parent's houses in order to live on their own and start making their own life decisions. In my opinion, no other age group seems logical.

Once someone reaches the teenage years, they become pissy and rebellious. If this happens to lead to atheism, then great. However, once someone grows up to the 18-25 age group, most move out and start living on their own. So they have no more reason to be rebellious. Why would they remain atheists then? This should prove that atheism is not a fad or something that will fade. It is an idea that, once accepted, remains with you forever.

The college student age group seems the most "new atheist" potential because they are learning who they are and how to live their lives. This leads to all sorts of experimentation, and not just sexual as most people would imply from this, but also experimentation in religion. Personally, that is where I first raised questions about religion. Although, I started earlier in freshman or sophomore year of high school. Experimentation and progress is a good thing.
