Martialis asked what we should do about the Christian extremists like the ones praying death on Obama...
Magic. We should do magic.
Gaap to release the spirits they've bound to their missions, Michael to enlighten them with the true message of Christ and to defend their victims, Cassiel to bind the bastards, Sammael to strengthen the warriors on the front line and to bring swift and just victory, Raphael to heal and to confuse their minds, to disrupt their communication network, and to bring a permanent Merc. Retro effect into their lives so they're too busy trying to figure out why nothing works right to pray, Anael to keep their prayers from reaching fruition, Gabriel to enshroud them in harmless fantasies.
Conjure Purson to reveal any local hotspots of prayer warriors, conjure Paimon, Aimon, Oriens, and Egyn to confound their lives, call upon their daimons to drive them into the true presence of God where they will see their actions for what they really are.
Ideally you'll be healing them so they not only stop what they're doing, but begin to help instead. Ideally you'll be in a position to love them completely and take responsibility for aiding in their enlightenment.
But it's better to do something than nothing, so just do something.
