This is why Christianity is relatively unsuccessful in parts of the world that aren’t directly or indirectly descended from the Roman empire (India, Japan, etc.).
One counterexample is South Korea, which is about 30% Christian, and where Christianity seems to have spread largely peacefully.
Christianity’s fairly common in sub-Saharan Africa, too, which did get colonized by European powers but which I think is fair to call culturally independent of Rome if India is. Conversely, North Africa was under the direct jurisdiction of the Roman Empire for a lot of its history, and it’s now overwhelmingly Muslim (though small Christian minorities still exist; e.g. the Egyptian Copts).
