If you stopped the indoctrination of children, religions would die within a generation. You’d just be left with fringe cults here and there that we’d laugh at.
Sounds like something that happened in ex-republics. For example during 2023 cristmas 1% of citizens visited christian churches in my country. And considering source(police) this number is probably inflated.
Relative to countries where many people visit church every week we have pretty secular society. Meanwhile fe(de)ral propaganda will continue to sell bullshit of “staples”.
