Provide evidence: existence of the Spanish Inquisition. Expulsion of Jews and Muslims after conquering Granada. Expelling the Moriscos regardless after converting to Islam during the reign of Philip III.
The Spanish Inquisition cannot be compared to the brutality of Crusader massacres like the Albigensian Crusade or the massacres of Non-Latin Christians, Jews and Muslims during the First Crusade. The
Spaniards didn't fully expel the Muslims until the 17th century.
Philippines turning into a country of 85%+ Catholicisim as well as most of Latin America until independence.
Except it took them three centuries to do so in both of them, the opposite of a swift conversion and even then in the Philippines syncretism is still strong while there's still a large Muslim minority.
Philip II willing to make not even the slightest concession in the Low Lands because he does not feel to tolerate any Protestants in his realm.
The issue of Holland transcended religion. During the Italian Wars Spain didn't make any accommodation with equally Catholic France for decades until they ended. Spain still tried to make as few concessions to the French, even after the French remaining Catholic, even after the rise of Cardinals Richelieu and Mazarin. Spain also did make accommodations with Protestant England after the death of Mary I. Although they ended up invading England, this was over the issue of the English attacking Spanish colonies and supporting Spain's European enemies. They didn't invade England the moment Elizabeth ascended and declared England Protestant again. Also, since clearly you just don't mean Philip II, we have over-Catholic Charles V
sacking Rome to punish the Pope. What a good Catholic indeed.
If this is not enough then there is no point in discussion.
Sorry but it's clear you're overstating your case, especially because you clearly are ignorant about Latin America. You also keep failing in producing evidence that religious intolerance will somehow make the Spaniards unable to keep Indonesia. You only keep saying religious intolerance somehow fails in keeping territories without providing examples of this occurring. Showing examples of religious tolerance keeping territories is not the same as showing examples of religious intolerance failing to keep territories.
How was Latin America multi religious? The Evangelist groups only entered Latin America after independence from Spain. If there were pagans as late as the 1800s it is likely because Spain could not reach them. Kinda hard when the landscape is big and people live in remote areas and jungles.
Because indigenous religions like the Mayan religion and the religion of Pachamama still exist and because African religions like Santería and Vodun still exist, and they were influential during the Spanish colonial period with the Spaniards tolerating them. They weren't small either. Sorry, but again, you clearly don't know what you're talking about when it comes to Latin America. Mayans for instance tried to create a separate state in
Quintana Roo during the 19th century. Before them, we have the rebellions of Tupac Amaru and Tupac Katari of the 18th century inspired by the Inca religion. During the Cold War, we see guerrillas influenced by indigenous religions. Today the cult of Pachamama is recognised in the constitution of Bolivia, and it is widely followed in Peru and Ecuador too. Heck, we see Mayan elites and Spaniards themselves creating and preserving Mayan religious texts like the Chilam Balam and Popol Vuh, which are still used today by Mayans in Mexico and northern Central America, and in the latter Mayans are no small minority but make up almost half the population. Meanwhile, the African religions of Latin America are so followed
they have been proposed as world religions. At best, you can say religious intolerance is feasible with a multi-religious landscape. You also have this idea that the Spaniards swiftly converted Latin America, but three centuries is not swift and seeing how Latin America to this day is still multi-religious, it's clear the Spaniards largely failed.
So again, religious intolerance is no obstacle to keeping a territory, nor were the Spaniards overzealous with their religion to the point they would give up holding a territory because the locals don't become Catholic. Nor is Islam going to make Muslims magically able to oust the Spaniards because they don't want to be Catholic.
