That's exactly what I mean. I'm not directing the situation, but will be participating.

I'd like to confront and see people confront her religious bias, without the result being excessive flame or her being backed in a corner without a chance to even marginally nudge her mind in the right direction. She's smart, will not make explicit religious statements, and will back her claims with cherry picked reseach. Naturally the level of mindkill will depend on other participants too, and I will treat this as some sort of a rationality test if they manage to keep their calm. If they lose it I guess it's understandable.

I guess I'll be using lots of some version of "agree denotationally, disagree connotationally".
