I also grew up atheist in a country where it’s not OK to be secular.
My only advice to you is this: Don’t talk about religion at all. Don’t try to find other atheists; look for people you get along with and enjoy being around; don’t talk to them about religion.
I don’t love quoting NDT as he can be polarizing, but he said that non-golfers/skiers don’t gather and talk about not playing golf/not skiing (paraphrasing). https://youtu.be/CzSMC5rWvos
The last atheist I met and hung out with at college had his whole identity wrapped up in atheism; it was uncomfortable; he also had some undesirable qualities that he used his atheism to excuse. I’m not looking for an anti-religion club, I’m just not religious; maybe you are looking for a “club” though, but I wouldn’t recommend it.
Just live your life and surround yourself with supportive, good people whether they are atheist or not.
Sometimes the operator is in another state! There was an article I read a while ago about… maybe it was Carl’s Jr.? but they were saying that the drive thru operators were in call centers in states with a lower labor cost.
Not exactly uplifting, but “yay capitalism” I guess.
