Recently my friends and I had a “theological raclette” - we met and had raclette whilst discussing religion and related questions. Our group consisted of three atheists (my girlfriend and me amongst them), one agnostic, two people that were vaguely pagan/Wicca, two Catholics and a general non specific Christian.
We all wore badges with our name and what we believed in, the pictures are of mine and my girlfriend’s.
The evening was great - we discussed various topics (how our beliefs developed over the years, abortion, the separation of church and state…) and stayed respectful throughout. We are all still friends and I actually feel like I got to know some of them a little better.
So yes - it is possible to disagree about religion, the church and whether or not there is an afterlife without condemning or ridiculing each other - especially if you’re consuming big quantities of cheese, potatoes and wine during the discussion.
