What happened was that I saw this forum where 1 person, person X, thought characters A and B would end up in a relationship and then another person, person Y, who didn't think so, misinterpreted person X as saying 'Even though I don't have basis to think A and B will end up in a relationship, I like the idea' and then criticised person X for the desire not the prediction.
My goal is to ask for a term to distinguish the ff 2 cases of shipping:
Prediction: I think characters A and B will end up in a relationship (eg HIMYM / HIMYF; Definitely, Maybe; The Quintessential Quintuplets), but I don't necessarily have any opinion about this relationship (eg whether it is better than another eg a possible relationship between characters A and C).
Wanting: I would like characters A and B to be in a relationship. I think they will be good together. I think that this relationship would be better than a possible relationship between characters A and C.
Usually when people say they 'ship' A and B, it's more of type 2. How would someone distinguish themselves as a Case 1 shipper aside from linking to this Stack Exchange post?
But then I realised I can actually generalise this question to asking how to distinguish thinking something will happen vs wanting something to happen. How do I do this in general?
Guess: 1 idea I had in mind is using the terms positive vs normative statements. Positive is about 'what is', and normative is about 'what should be'. For example in economics (whence positive vs normative economics), 1 might say a stock price is this, but then another might say said stock is undervalued and should be priced much higher. Can positive extend to 'what I think will be'?
If so, then I guess for the case of the shipping I'll just say positive shipper vs normative shipper.
I actually did sort of ask this before in English SE and then in Law SE when I asked the opposite of 'argumentative' and then I got 'factual'. I think 'factual' has a similar problem to 'positive' in that they're both talking about 'what is' but not necessarily 'what I think will be'.
