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.)
It’s a little tradition and a bit of a promise, even though vague and breakable if we’re honest.
I wouldn’t have done that personally, I would’ve had it required that immigrants sign a doctrine as to whether the immigrant is going to uphold the laws of the country they’re migrating. Failing to do so would be automatic deportation.
