Fundies change their minds all the time. I personally know two people who were raised in the church and believed into their twenties until they came into contact with free thinkers at school and learned to think objectively.
If you look at the stats, the number of Christians is declining at a fairly decent rate. millions of people are leaving their respesctive churches and admitting they just don't know and there's no logic to it.
This is an argument the Atheists are wining in the big picture, besides, arguing with fundies can be really really funny.
