Ayaan Hirsi Ali showed great insight when responding to a question as to how to get others who struggle with false systems of belief to come out and leave those false systems said that in the same way she stuggled with the dissonance caused by the difference in what she felt and believed in her own heart and mind with what she witnessed with the false system of belief around her... she suggests:
THE BEST MEANS of challenging and empowering people to examine their own position, beliefs and practices (along with their contentment vs. discontentment to remain or change their profession/position) is to CREATE AS MUCH DISSONANCE AS POSSIBLE for that person..." (my paraphrase)
I submit to you THIS IS TRUE not only for those who want to convert people from false faiths to atheism, but to convert people from false faiths (including Atheism) to TRUE FAITH (Christianity)!
DO IT!!! (Look for EVERY possibility. Take EVERY opportunity!)
Ali's thoughts are not original here. The wisdom is referred to in God's Word. 2 Cor 10:4ff "The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive EVERY thought to make it obedient to Christ."
