There isn’t always conflict. I’m an atheist. I have a very good relationship with my neighbours. Upstairs are JW’s, and my new neighbours are delightful and are 7th Day Adventists. It does make it impossible to have Home-owner’s meetings on the weekends, but we make due with Monday evenings.
That being said, back in the ol’ USofA, where my family is, I have sisters, brothers and sisters in law who think I’m guilty of child abuse because I’m not raising my child Christian and nor have I baptised him. So, yeah, sometimes it does come up.
There is a tradition here in Norway where when children reach the age of 14 or 15, they go through a program, traditionally Christian, to be ‘Confirmert’ or Confirmed. It is historically a rite of passage into adult hood. It means you no longer have to go to bed with the children, but can stay up with the adults and ‘party on’ into the evening wee hours. These days there is a very large Humanist Association, one of the largest in the world, actually. https://en.wikipedia.org/wiki/Norwegian_Humanist_Association They run a program so teens can still go through being confirmed by sitting in classes to make them more aware of the world around them, teach them more empathy and open their eyes to the role they take as citizens in one of the most advantaged countries in the world. The year my step son was involved (he couldn’t partake fully due to his profound issues with ASD) they had the kids walk all day and into the night where they met several problems meant to simulate just a little of what refugees face when they have to flee their homes in war torn areas of the world. It was awe inspiring and tear rendering, I can tell you.
