Well, we read Jehoshua's essays on it. That's what we have been basing it on. Thanks for clarifying the Brazilian conception. Don't be afraid to contradict the Pope about what is fundamentally a Brazilian movement. The former government of Chile and current government of Nicaragua are both far from what you just described.
How would Brazilian Moralism be applied to completely Protestant of Muslim nations? Or those with a heterogeneous mixture of religions, like Argentina and others in Europe?
Brazil does oppose the Papacy on some of these issues. The Pope is an equal partner in the Moralist International, not a ruling figure. This comes from a long history in CI of South America being rather indifferent to the Papacy. It is a European thing, but we respect the Pope regardless.
Brazil defended Moralism in Nicaragua not because it was the perfect, but because it was there. It could not be allowed to be killed by PADA. It was simple sphere expansion. You have to understand that governments do things for one reason while stating another reason altogether quite frequently.
Protestantism, Greek Orthodoxy, Islam, or Judaism all have fundamental similarities that could be applied to Moralist doctrine. It isn't an ideology that says, "You must be Catholic or else!" Catholicism just happens to be the dominate religion in the nations where this ideology developed and has given it a flavor that favors Catholicism. But true Catholics are no different, traditionally, from the other religions in their views on society and peace and all that spiritual jazz. Christianity is a peaceful religion where respect of your neighbor and acceptance of their flaws is the norm. Democracy is fairly Abrahamic if you break it down and Moralism uses commonality between them to promote moral, healthy societies based on kindness, charity, and cooperation. War is a negative, but defense against the rival ideologies is a must. Proletarism and Absolutism are threats to the entire world and it is a moralist's calling in life to see those resisted, first with words and diplomacy, but then with force as a last resort.
So I'd say, Moralism is easily accepted in nations such as Argentina. Social programs, public works, healthcare, pensions, and education are all fundamental rights in the eyes of Brazilian Moralists. The economy attempts to be as free market as possible, but you have to consider it as a moral capitalism. In this system the people demand protections but it is expected that in an ideal moralist economy the government would not need to interfere as the supplier-consumer relationship would be governed by moral practices. It is a pipe dream, yes, but the government actively works to provide the healthiest and most moral form of society they can within the limits of their power. Drugs and alcohol negatively impact the health and morality of a people and must be culled by the only force that can: government.
It is all rather Christian Utopian, if you want to consider that. It has flaws, but it certainly isn't nationalistic, fascist, racist, sexist, or warmongering.
