yes, you’re very correct on that. I failed to write it in a way that gives space for exclusions. I wanted to write something like “from the people who migrate in mostly atheistic (or at least less religious) countries, when they continue being fanatics in their religion, then this decision is by choice”. Because they are now in a place that if they want to get rid of that culture, it is easier to do it.
Sure, there are people who migrate because they want to leave from the oppression they experience in their home countries and they decide to follow a completely different lifestyle but these are not the majority. But they surely exist.
