But that's not fair and it's not cheating. For the Crusaders, to switch religion (at least from Christianity to Islam) is probably more stable since the population was Islamic partly to start with, and had Catholicism forced on them.
Ditto for the former Byzantine Anatolian cities to force conversion to Islam.
You do realize that this will basically force people to switch religions during the first move after dealing with the civs they have contact with. E.g. for Bohemond, the above technique still works since they will have no cities (i.e. no revolts) if you don't capture Antioch.
If anything, any city that has the new religion you're switching to should be celebrating "We love the Monarch/Theocrat!" Day.![]()
Revolts aren't a very big issue (they're just one-time revolts, not flips, and only in cities with Christianity). Also, you can't convert to another religion if you don't own any city. So you can only do it after capturing Antioch, or after the flip - but it's the unit betrayal that hurts most i.e. you will lose all your knights and some infantry (they've come here to fight muslims, not join them).
You can still do it, just have to be careful about timing, so as to not convert while at war, or compose your army of militia and mercenaries, rather than Knights/Templars/Hospitallers.
