No, you are complaining about the architectural style of the Church building in this topic, which is in your view apparently not "historically correct". Your point being that the Tropico Island does not have an actual history that would justify having the Iberian-styled Churches, as the Churches would be constructed after 1950 and not by the Iberians.
The flaw in your idea about this is that there is no reason to mark these Churches in Tropico as an anachronism, it's not because Tropico is a new island that its buildings can't be designed after or inspired by the 'traditional' architectural styles.
