Not objecting to your comment, only that a history of the importance of the religion aspect of Crimea gives insight into it’s future, and the rest of the world.
Catholic vs. Orthodox disputes can make things somewhat testy, yet the most devoted of both faiths respect one another as do the most devoted Evangelicals. (There is a significant evangelical presence in Ukraine.) It’s “Churchianity” people that get in the worst fights over religion. Those who are on the level of seeing a passion play as presenting a figure who must be humanly avenged.
