The people reading “foreigner” or “other races” into the Demons are normally the dumbest motherfuckers in the world. So buying into that discourse is dangerous in that you let other dumb idiots think they are justified. But I personally find the demons fascinating because their presence is a reminder of the actions and ramifications that take decades, if not hundreds, if not thousands of years to develop. It’s obvious a demon saw Frieren hide her powerlevel and then reveal her true scale. So in a long enough timelines demons will adapt.
