If I said that I'm an atheist in your nation?

[Greenwichian Arcadia]

Probably no one would notice such a common stance.

[Suid-Afrika and Rhodesia]

Somone would probably say something like "You make me sad"

[VlaRiSsiA]

Execution of you and all your family members. Everyone must worship the ogrelord, meaning that if you are an atheist, you don’t revere our ultimate supreme leader. We crucify those who don’t worship the great leader and force their family to dig their own graves.

[Roegerland]

Depends who you say it to, though the most common response might be something along the lines of "Oh right, okay"

[Starrden]

“Eh. Whatever.”

[Revolutionary Arkania]

Most people wouldn't care. The traditionalist faction of the Eternal Revolution Party would try to crucify you on the next rainy night. Perhaps, if you fit other aspects, some factions of the ERP would invite you to join the party.

[Skillvio]

Other than the elderly or rural, poor folk, Albans are not very religious--if at all. A majority subscribe to the Church of Alba, but most parishioners don't attend services regularly. You would encounter little resistance or judgment.

[Watchelan]

"As opposed to what? ... Keep your voice down, son."

[Penguin Union Nation]

Someone would say, “What do you want, a medal?”

[Dzigerski]

You would probably get some dirty looks here or there from the older folks but nothing much would really happen.

[The Municipalities of Antarctica]

Very few, if any, would care at all. Those who do care, would be those scolding you for focusing on that instead of survival in this bleak place.

[Deacarsia]

You would be deported.

[South Acren]

Depending what Universe your in, its either a stoning, a burning at the stake, forced conscription, or prison time. Worst that could happen would you would be sent to meet one of the Horsemen themselves, and I have yet to have someone return from THOSE meetings.

[The Sladerstan]

A Creation Scientist may hear you and try to logically explain the existence of God (our Scientists are mostly Creationist) but, if you're lucky no one will even care but probably just ignore you. Unless you started cursing God and saying blasphemous things, then people will get angry.

[Kafair]

You'll enjoy our wonderful religious training centers and all the copies of The Flare Scroll you could imagine!

So its better to just keep that to yourself, yah

[Republica Federal de Catalunya]

Something similar to:"...And?" or "It's not my business" or "I don't care".

[Kantani Civilisation]

People would probably look at you awkwardly and wonder why, but it's not illegal or anything.

[Talitoa]

Nobody would really have a problem, unless you started to denounce it. People here think religion is a thing people can decide for themselves and can be a good thing.

[Drew Durrnil]

people won't care

[Monsone]

Nothing because of religious freedoms and the fact that 47% of Monsonians are atheist.

[Aeritai]

You would get a few stares from people if you said it out loud and would just move along. While Aeritai's population is mostly Christian being a atheist here is not punishable.

[White Sun]

At best, you'd get a shrug from passers by.

[Accipitridia]

The people of Accipitridia would honestly not care. They have better things to do other than punish people for their beliefs.

[Gnollrike]

Depends... are you a rich atheist?

[Kathol Rift]

Almost everyone would agree with you, and the ones who aren’t atheist, aren’t religious enough to make a fuss about it.
