It seems to me that many people in general do just tend to be ignorant of such things until they are personally affected and thus finally learn for themselves. Anyone mentioning those realities to the ignorant before they were personally affected are easily forgotten/dismissed.

Even further, even if you DO have automatic citizenship someplace it’s STILL difficult to get through all the red tape if you actually want to move there. Documenting it is one thing and wanting to move quite another.
