To be fair the masses didn’t have much of a choice.
Certainly Northern Europe was christened at the point of a sword. Also, were not allowed to trade further south if they did not accept this new monoteistic faith.
I grew up in a lutheran home, to me everyone were christians, except me. I remember arguing with the Sunday school teacher about stuff that Did Not Make Sense 😄
my parents were embarrassed.
I left the state church when I was 14, and the clerk was very puzzled when I didn’t leave to join another religious «club», I just wanted to leave for «nothing».
Very liberating, so I understand where you are coming from OP.
My family aren’t fanatics, though. So even if we don’t understand each others viewpoint, and in the past often discussed matters very eh fiercely, we never fell out. I really appreciate my parents for encouraging curiosity and debate - we talked about all sorts of difficult subjects and learned to both talk and listen. The debate could be heated as we disagreed, but it was the case being discussed. Always the ball, never the player.
Ironically, this left me ill equipped to deal with narcisists (and psychopaths) as they always attack you as a person and never stick to what you actually need to discuss. But well, now I know that too.
However, now I work in a Christian organisation. I was up front in the interview that I hold no religion, but that I respect the religious ethos and will abide by that.
I am still critical of many aspects of the large religions of the world today. And I reserve the right to voice those criticisms, without attacking believers.
Of course, some people do feel attacked when facts are pointed out.
