In Civilization VI can I found a religion in a city that already has one? Will the city have the just-founded Religion, despite it having only one follower, or will it stick to the religion of most of its citizens, effectively pre-emptying the spread of the new Religion?
Civilopedia seems to say conflicting things about this:
Founding your Religion: "Once your Religion is founded, all of your cities with Holy Sites will automatically convert to the Religion"
Religious Units and Pressure "If more than half the citizens in the city are Followers of a particular Religion and that Religion has the majority of Followers in that city, that Religion will become predominant in that city"
So, which of these effects predominate?
