Sponsor a Debate or Speaker
College kids love debates and media often cover them! The objective doesn't have to be changing minds but just to raise awareness of the atheist movement. Here is some advice for managing the event:
Rather than hold it at your religious opponent's church, find a more nuertal spot like a Unitarian church, a college lecture hall, an outdoor stage or a bookstore. Advertize it often to your local freethought club, as well as the general public.
In developing a format, remember to structure it to avoid shouting matches. Loud and rude does not equal right. Also, don't let rounds go on for too long. Each debater wants to be able to remember all the points made by his/her opponent so they may rebutt each one. Pick a topic that is clear and has wide appeal, define vague terms like "God" beforehand so debaters can get on to debating a conclusion at your event. As in Presidential candidate debates, keep rounds to a few minutes. Allow pleanty of time for a Q&A session at the end of the debate.
If you are interested in becoming a worthy opponent in atheist/christian debates, read over the Freethought Debater website for the basic arguements on several topics. Another useful tool would be the Atheist Debater's handbook. When seeking responses to common apologetic arguments you can search Iron Chariots for answers. The Kitzmiller transcript is the single greatest evolution vs. creationism debate I've ever read. Check it out.
FFRF Co-President Dan Barker, a former fundamentalist minister who is ideal for debating religionists, would do a debate a month if he had the chance. If you have a connection with your local university, try to get a student group or department to sponsor a debate. Dan gives many Freethought concerts at local U.U. and Ethical Culture congregations, colleges, etc., as well as speeches about the Foundation, Freethought and the separation of church and state.
Edward Tabash, a lawyer in the Los Angeles area, is also available for debates. ,a href="http://www.richarddawkins.com/">Richard Dawkins does the occasional debate as does Michael Newdow. The Non-Prophets may be another good source.
