Ladonia doesn’t refer Sweden as Uncle. In fact, Sweden acts more like a fatherly figure. But whatever you say.

One, I don’t appreciate your tone. I’ve already said before that my word isn’t law. This is a place for discussion, not me indoctrinating or forcing my outlook onto others. You guys are my check and balance, and in no way are you obligated to agree with me.

Two, calling someone an uncle is not mutually exclusive from being a father figure. They can go together.

Three, this is the strip I used.

Here’s my explanation:

My justification is that all the other Nordics are waiting for Santa Claus and Finland to appear. Ladonia generically refers to them as Uncles.

Denmark comments that any kid would refer to them as an uncle. Ladonia later refers to them as Swe’s friends. I think this correction and differentiation on Ladonia’s part is him being embarrassed by Iceland’s initial confusion at the label of being called an uncle. 

Considering how Ladonia first uses uncles generically as they all wait, which happens to include Sweden, this is why I believe that he grouped them together to fall in line with how he perceives his relationship with Sweden. Like you said, Sweden acts as a father figure to Ladonia, but given how much pride Ladonia takes in his independence, I don’t think he sees him this way.

Further, what differentiates Sealand and Sweden’s more explicit parent-child relationship is that Sweden actually adopts Sealand, not to mention the fact that Sealand isn’t autonomously recognized.
