In whose favor? Do you seriously want to defend the direction North American culture is going?
Besides, you're also comparing a Spanish model of evangelization, colonization, and culture, with an English one. If you imagine that the English Reformation had never happened, North America would still have turned out very differently from South America.
“In whose favor? Do you seriously want to defend the direction North American culture is going?”
Well, now you are playing games, narrowing the focus to how the culture “is going”, right now, and in the future. Seeing how secularism has increased notably in recent decades, that isn’t a sensible thing to focus on when you are talking about the impact of the majority religion on the state of affairs. If you want to compare how North American Protestant nations did against South and Central America Catholic nations, over the course of their whole history, then yes, I do think it’s comes out in our favor, by a vast margin.
Even if we were to limit it just to the current state of affairs like you wanted, I still think we come out far ahead. There are no states in Protestant North America where communist insurgencies openly operate, or where military juntas have seized control, or where narco cartels control the economy. There are no countries up here where people live in shanty town ghettos with no plumbing, there are no packs of orphans running the street picking pockets, and we don’t worry about armed gangs kidnapping us for ransom except in the rarest circumstances. Go down to the Catholic countries, and those things are facts of life.
