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

[Ilyvan]

It depends where you are. In the north, particularly around Mystyme and Thyrne, you would probably be lynched. Down south in Gytesbyrd or Welyth you'd be mostly tolerated, although viewed with suspicion

People are free to have their own views so long as they're packing heat.

“Good job, you get to live!”

Yes, religion is banned and punishable by death in Caleon.

[Logikie]

you would be welcomed with open arms comrade!
no false gods, no fairy tails, science, progress, and socialism!

[Akrafjall]

It depends on who you say that to.

• The 54% of the population who are religious would probably give you a disapproving look,
  -
• The other 46% of the population who aren't would shrug you off and categorise you with them weirdo vegans, and;
  -
• The police would check you for drugs.

Nobody Cares Anyway

[Skolipendra Organization]

It's a fair assessment. Though you'd likely be serving directly under a magical being, who will be quick to inform you that "god" is a title held by a number of individuals, it is perfectly fair to reject belief in the divinity of those who hold the title of "god". Especially considering that a perfectly normal human could be given that title (and the title comes with no powers of any kind.) You'll even get support from Branch Commander Anisa Al-Samad, who supports state-atheism. Most people in the Skolipendra Organization just wouldn't care, however, though a few might question you about it considering how much magic you will have seen by that point.

Post-democracy: Occasional disapproving looks

[Breen]

While there's no explicit law against being an atheist, saying so would violate Breen's Lèse-majesté law because the Monarch is considered descended from the Gods and by extent is divine. So your head would be swiftly removed.

[Rising Palms]

As long as you're not hurting anyone or are suffering yourself because of your religious beliefs or lack thereof, then there's no issues

[Kuominwave]

You would be seen as normal.

[Brightlake]

No one will respond to the statement since it is a fundamental rights of Brightlakean to believe or disbelief any religious teaching.

[Dee Alleng]

The majority agrees.

[21st Century Rome]

Well, you might be fine, or the nuke cult might nuke you. Depends how they're feeling on that given day and/or if they've wiped themselves out again.

[Elenir]

Your insides would be used to feed the rest of the population.

[Gurori]

"Cool." Or something on those lines, that's the reaction you'd get. The Guronese are super chill about that kind of thing.

[Ardrentt]

Minimal reaction, most people would just wonder why you brought it up?

Religion's certainly a heavily discussed topic, but at this point the tensions of the past have long dissipated given the emphasis of previous governments on facilitating better debates and integration between disparate cultural groups.

Your insides would be used to feed the rest of the population.

[Tankium]

You would be arrested for 5 years

[Rastrian]

In Rastrian, much of the population is already irreligious, with the rest being of either various tribal faiths and some usually quite progressive Christians, so you most definitely would not be alone. Moreover, there is virtually no religious unrest or friction. As such, the majority reaction would be either disinterest or quizzical stares as people attempt to guess why you would mention such a thing. In very small minority cases, you may get eyerolls or facepalms, as the only people likely to say such things would be ignorant foreigners wanting to start an argument. But basically, nothing too terrible.

[Felsigberg]

You would be given weird looks, berated, spat on. It's even worse if your Muslim

[The Xenopolis Confederation]

You would be given weird looks, berated, spat on. It's even worse if your Muslim

That's a bit rude.

[Great Eddy]

Literally nothing.

[Auspelia]

Nothing much would happen but it would depend on where in the country you were. Like the United States, Auspelia has a 'bible belt' of socially conservative and extremely religious states. These are:

Capricornia
Kingsland
The Northern Territory
Eastern Auspelia

If you said you were an atheist in these states you would probably be met with some odd stares but chances are no one would actually do anything. These states are very similar to the "deep south" of the U.S so imagine if you said you were an atheist in a state like Alabama or Mississippi or Georgia and the reaction would be essentially the same as if you said you were an atheist in one of Auspelia's 'bible belt' states.

If you said you were an atheist in Auspelia's more secular and liberal states, no one would really give a damn.
