If you're here in the U.S., you'd be wasting your time. And I'd probably agree with them. I guess the best you could possible hope for is to sue on the grounds of emotional distress, but then you admitted that as an atheist you don't believe in Hell. And then you'd have to pick one church where the pastor specifically said that if you don't believe then you're going to burn in Hell. If you tried to name "Christianity" as a defendant, you'd be as loony as that crazy lady who tried to sue all homosexuals on behalf of God.
Christian apologetics is the art of rolling a dog turd in sugar and selling it as a donut.
