You can definitely exit religion even growing up in a heavily religious environment, it seems you did in your own experience right?
I grew up in Texas surrounded by Christians, while I was lucky enough that both my parents are… Not religious per-say (but maybe deist?) I wasn’t forced into religion either, I went to church many times with family and friends but never really “bought it” and eventually ended up as an atheist. My wife was Christian when we met and eventually also came over to atheism eventually after many many discussions and videos and evidence etc… people can be deconverted, it just takes a lot.
I think the Internet helped me to not fall into the trap personally, and definitely helped with getting my wife out of it.
