again, Anglicanism in south Africa versus the dutch reformed church (cape dutch and boers) Shia and sunni islam (with the barakazi dynasty essentially making all pashtuns sunni and reducing shia pashtuns to a vestigial minority) Islam vs christinaity ( in the Balkans religious conversions to either where a common affair, under the Austrian the catholic Bosnians had a marked increase, under the Ottomans many also converted to Islam by the same token many also converted away from islam post independence of their country) Islam and chrisitanity again, this time in west Africa, and do note that all of the examples given come from countries that where not particularly zealous in their conversion attempts, second none where saying that mass conversion where common merely that they did in fact happen, and that therefore should be achievable in game, a country (e.i a player) that wants to should have the ability to be the "exception" as you put it, and unless yuo are going to affirm that some religions are just better than others, any religion should be able to achieve it, and any religion should be susceptible to it.
