Hello!  This is the public page for Contra Costa Atheists and Freethinkers (CCAF).  Most of our events are in the Walnut Creek and Pleasant Hill area of Contra Costa County, California.

You may find our group interesting if you subscribe to the idea that knowledge of reality advances by way of scientific inquiry.  We are particularly skeptical about references to religious dogma or supernatural phenomena as a useful explanation for anything — to say the least.

We especially encourage you to disclose your atheist, skeptical or freethinker views as a method of educating the uninformed public about who we are — and that we are many!

As we have learned from the LGBT community, an effective strategy for promoting positive change is to come out, stay out, and speak out. The Openly Secular campaign provides one way you can come out and tell your story:

CCAF endeavors to provide informative and enjoyable activities that promote opportunities for faith-free discourse. Our activities have included thought-provoking talks by invited speakers; discussions about various topics, including videos and books; group rendezvous at clubs, movies and restaurants; organized hikes and tours; and just getting to know and enjoy each other at parties or salon discussions at a member's home.  Suggestions for new activities are always welcome, and we encourage member-initiated events.

If you want to join CCAF, you will need to be signed-up with Meetup.  However, CCAF is a private organization, and requests to join will be reviewed.  This is to provide a measure of security to members who are not yet ready to announce their views to casual online visitors.  This is also to discourage commercial solicitation or tacit endorsement of weird viewpoints.

If you want to join, please be prepared to provide an image with your request.  While a photograph of yourself would be appreciated, you may use any legal picture or graphic that you like.  This removes the unsightly and distracting question mark or blank square that would otherwise be attached to your name.

Also, please be prepared to answer a few simple questions.

Although CCAF is affiliated with other atheist and skeptic organizations, we do not share our membership list.  Our general focus is to provide a safe local community forum.  But we are also ready to inform and mobilize our members for action if local issues directly impact the status of atheists and freethinkers.

A brief history:  Beginning in 2006, CCAF was originally known as Atheists and Freethinkers of Contra Costa County. It was organized around an email list of interested individuals.  In July 2011 CCAF migrated to the Meetup platform, which provides useful membership and organizational tools.
