Unless you have a lot of money... Just stay in the USA. You do need to move from Florida though... How about a nice blue dot in a sea of red, north of you?

If Norway weren’t so cold, that would be my first choice. Better to just find something closer to home where agnostics and atheists are more welcome.

I can in a way understand what you mean. And I have known quite a few that are very polar, in that they will take one side no matter what evidence may be presented.And shun others that hold the same ideals.
In my years, the one thing I've learned, is that of the very few that I will call "friend", are people that judge each other, not by their religious views, and not by their political affiliations.
Rather, by the human being they are.
Some are very religious, some are not, some are far left, some are right.
But the real thing that unites us, is how they treat others regardless of any opposing views they might have.
That is a key factor to me.

With that notion, I honestly believe there is a spark left in humanity, and for lack of better word togetherness.
And while I will agree, religion is a huge culprit in the dissonance of many people. IMHO, finding a common ground on something other than religion, or a political stance, can pave the way to, again for lack of a better word, acceptance.
Granted, many in the world are not ready for that, but the numbers of those that do, are growing exponentially.
Sorry, I'm not sure if that makes any sense. sometimes my brain races farther, and my ability to form a thought.
But I still stand by what I said about finding "common" ground.
Look far enough, and it'll be there.

I have a somewhat similar feeling! I did leave the South and for that same reason, Christianity has become almost a disease (my opinion) in the South. However, here in the Southwest, that Evangelical leaning is alive and well, just expressed with less trying to ‘save my soul!’ I just don’t bring up religion unless someone is speaking in discussion of religion.

Here is good

Firstly, if you are looking to relocate internationally what have you got to offer? Unless you’ve an outstanding ability, in a necessary profession, or you have an Australian spouse, Australia is probably out.

What can you give rather than what can you get would need to be your motivating factor. Or as Seeker says, move to Colorado!
