Fellow non Muslim Algerian here (F in my late 30s) living in North America. I’ve met several non Muslim (primarily Jewish) Algerians since immigrating West. We left Algeria during the Black Decade. I’ve been back once to visit and stayed with a friends’ family. No one questioned my religion or lack there of. They were just happy to host me, take me on adventures, and ask me questions about my “new life”. Religion wasn’t even a topic of conversation. I did hear the occasional marriage jokes (being a single woman in my 30s is a trigger for jokes apparently haha). I hate that there are Algerians outside of Algeria who made you feel excluded because they don’t speak for a whole country. I was sad when I returned because it no longer felt like home to me, rightfully so because it had been almost 20 years before I could bring myself to go back. That being said, my heart still has ties to it, and I still try to embrace the culture in any way I can (food, clothing, music, etc). So I say go for it! You have nothing to lose!
