We do not have 2 different religions yet.
You are right, but the title of this mod is "
Religion and Revolution" and at least the first part of name should present in more detailed form.
How to correct this problem? I see a number of variants and here one of them.
We add a new class,
RELIGIONCLASS.
Thus, we can present three major groups within Christianity, namely,
Catholicism,
Protestantism and
Orthodoxy. We cannot exclude the last one, because Orthodoxy also was presented on American continent during colonization era.
Thus,
all European civilizations listed in CIV4CivilizationInfos.xml will have a new tag depending on their
main RELIGION, for instance,
Catholicism for Spain and Portugal
Code:
<Religions>
<Religion>
<ReligionClassType>RELIGIONCLASS_CATHOLICISM</ReligionClassType>
<ReligionType>RELIGION_CATHOLICISM</ReligionType>
</Religion>
</Religions>
Protestantism for England, France and Holland
Code:
<Religions>
<Religion>
<ReligionClassType>RELIGIONCLASS_PROTESTANTISM</ReligionClassType>
<ReligionType>RELIGION_PROTESTANTISM</ReligionType>
</Religion>
</Religions>
Orthodoxy for Russia, if this civilization will added later
Code:
<Religions>
<Religion>
<ReligionClassType>RELIGIONCLASS_ORTHODOXY</ReligionClassType>
<ReligionType>RELIGION_ORTHODOXY</ReligionType>
</Religion>
</Religions>
When these correction will be done, we could add a simple condition for "Stirring Up Natives":
"Stirring Up Natives" is possible only, if the different religion is present in the village.
This addition looks very logical and historically correct. The Catholic priests were guided by the instructions of the Pope, not his European king. They cannot create any problems each other because in such case they are fighting againt Pope, that was impossible.
Also I see it more like that:
The Missionaries of a Village will prevent "Stirring Up" no matter what Religion the other Nation has,
because they want to prevent trouble to their home country.
(And since they are already in that village longer, they are more influential in that village.)
You are right again, but your variant is only a part of more common idea, I described above.
