Basically: In some countries, the pledge is with the constitution or the people, but in others (like constitutional monarchies), its a pledge to the (constitutional) monarch and their successors.
What is your opinion on this loyalty pledge? Do you believe it’s a reasonable request?
(For context: My mother and older brother had to do the pledge to gain [US] citizenship so the idea of deportation isn’t looming over our heads. I didn’t have do it because I was under 18 and my mother’s citizenship status automatically carried over to me according to the law.)
Allegiance to a country is such a nonsensical concept anyway. What is inferred is an allegiance to a government. A government is delimited by time, so in theory you should need to reaffirm your allegiance each voting cycle. Furthermore, what does allegiance encompass? I do not know of a single government I would align myself so deeply with, that I would go to war for it for example. That doesn’t mean I dont like my country.
