You should be planning and sharing strategies with each rather than restricting this grave potential threat to a small group. I know atheists who home-school. But I guess it is what it is...
I understand why wrmfights would want a Caucus to discuss the vital topic without the RCs brick a brake messing up the topic...especially because so many who do home school are evangelical or independants and protestants...and in many cases Scriptures are important to these people and in their settings.
