foxholes
people say there are no atheists in foxholes. and that's probably true. right up until the grenade lands in the foxhole. then suddenly everyone's an atheist. i explain. you're prayersquatting in the foxhole to the almighty to keep the grenades out of your foxhole. but one lands next to you anyway. god has ignored you. not cause you're not a good person. but because he doesn't exist. and all your beseechments were for naught. now you have a decision. you can have faith that god will save you. that grenade won't kill you. except it does. you and all your buddies are dead. and go to heaven. which i guess, isn't so bad.
or you can temporarily drop the charade that there's an omnipotent omniscient being that for some reason cares about a worthless shit like you. and smother that grenade to save your buddies from also dying the real true death. they'll immediately go back to their fantasy believing you've gone to heaven. and thanking god for making the grenade land next to you instead of them. because if you don't, all of you suffer permadeath.
