I just politely laugh, and say well, good on him.
Tell them it is just a control method. I am no longer afraid.
If it happened, I would probably would smile and tell them I wouldn't be losing any sleep over it.
I laugh my ass off. I also love it when they ask, "don't you want to be saved?" "Hell freakin' no," I reply. "Saved from what? Logic, reason, critical thinking?!"
I say that their 'God' is nasty, vindictive and unjust, how fair is it that you can spend eternity in 'Hell' for sins over a few decades, I could never support such a 'God' and I would rather spend my time in 'Hell' with a clear conscience than sucker up to such an evil, wicked thing they call 'God'. To date I have never had a counter-argument other than a malicious "You are going to rot in Hell! Ha!Ha!"
Wow, I am not alone. Thanks for sharing.
I think I would tell them that if hell really existed, it would have to be the home of freethinkers, because that where you claim we're all going.
"Okay, you can believe what you want. When you can show something good God actually does on Earth, maybe I'll worry about death. 'Til then, eh."
I laugh hilariously while making "horns" on my head with my fingers, then I stick my tongue out, shake my head and growl.
