Atheists and agnostics are limited to Apologetics which is a good thing. Keeps things peaceful. We can all appreciate the ones who honestly admit they are not believers but come here to have cordial discussions with Christians.
But sometimes non-Christians slip into RR so they can argue a liberal POV in Politics and other areas. With the election season kicking in this will probably get worse.
Is it possible to require new members to first post their testimony of how they came to Christ in the New Members forum? Seems to me that would stop trouble makers dead in their tracks and they'd quickly go elsewhere for their "fun".
