Dan Silverman, president of American Atheists, applied for a New Jersey license plate that said "Athe1st". That standing for atheist, of course. It was originally rejected. Was it rejected because of some clerical error (the reason given later) or because it was offensive to a New Jersey state Christian employee? Hmm, who knows for sure. New Jersey isn't Alabama, but anywhere outside maybe the University of Vermont, sees a lot of anti-atheist hostility.
There is a new website called the Secular Safezone to help non-religious and atheist students come out as atheists. As I am sure you are aware, at one time it was very hard for gay and lesbian teens (still hard in some parts of the U.S.) to come out to their parents, family and friends. Well, it is even worse if you are gay and atheist, as being gay makes you more likely to question the perceived wisdom of the Christian bible.
But even if you aren't gay, but you are an atheist, you fear rejection. So that is what the Secular SafeZone is about, to provide tools for young adults to become open atheist and for others to support them. In fact, you can donate to the cause.
