jews: the heavily religious some effect but the transition is the easiest. the hard part will be losing all the holidays and the traditions more than the actual faith, but that will stay culturally instead, which is already the case for many. god won't have anything to do there, just pride.
christianity: most varied of all in both faith and results. protestants generally ought to end similar as the jews, catholics have the biggest trouble. mormons also get it bad but prob not as bad as the hardcore catholic base. you can expect many to kill themselves to try to prove there is a god even despite the proof.
scientologists: pissed that they now can't get away with some tax cuts.
muslims: middle east destroyed. biggest effect to the jews as well will be israel's destruction in the process.
buddhists: don't care.
hinduists: probably don't care, more cultural than religious anyway probably.
an overslimplication. and every piece of media would make it worse with a lot more doomsayers going 'well now without god that means people will turn into ANIMALS AGAIN OH GOD THIS WORLD IS HORRIBLE' until a generation or two pass and despite an immediate spike in crime (and suicides) in the US probably not a lot of overall impact ends up being had since we're mostly secular anyway. secular countries probably don't get impacted much because the rules are distanced from religion. we'll just replace any issues there and say it's part of culture instead.
religious heavy countries though are entirely ****ed and you do not want to be anywhere near them anytime soon.
