There's not much to misunderstand actually. If people argue that no, fp+ is the reason for all of their miseries, people who like fp+ just got lucky or must have not been able to do as much as with the old system, or there are more people complaining about fp+ so those who like it are mystical unicorns, even though those people who like fp+ don't agree, that's discounting their experiences. Pretty simple.
You can't tell me that positive fp+ experiences are valued as much as the negative ones when people say things like, "game set match" as if they're winning some kind of game lol. Or the majority of some people's whole post history is all about fp+. >.>
Its kinda crazy how you are conflating things, but that happens on these boards. "Game Set Match" was in reference to something else entirely, the idea that crowds have increased, that SB lines aren't increased due to FP+. The simple counter argument to which was, if crowds are increasing, shouldn't disney be keeping pace with attraction capacity increases ? But really this was just a side note, since just about anyone with any sense of logic or understanding of the system can see that FP+ increases SB lines on many attractions, while even slightly decreases it on some. Thats the impact of adding FP to more rides (and paper FP would have done the same had they expanded it to more rides) and of crown management.
But to the point you are actually referencing, now that we have addressed your unrelated tangent. You were talking about "Arguments to buy" vs experiences and preferences. As I said, no one that I have seen has said "you didn't get those FPs" or "you didn't have a good time" or "you didn't ride 10 rides" with FP+. On the other hand we have seen, in this very thread and others, "you don't need to book in advance" "You must be able to move things around because I was able to" "There are no lines at kiosks" "Fast pass+ hasn't increased SB lines" etc etc. When someone says "I got an A&E the night before we arrived" the response isn't "No you didn't" its "Wish I had that much luck" or "There is only so many people who can do that due to limited capacity" but if you say "there isn't/wasn't availability to move FPs around" the response here has been "there is lots of availability" or "its easy to move things around" which actually denies the posters experience. That was the entire point of the "I don't buy that argument".... because I didn't see it, haven't experienced it etc.
This does work both ways, people with negative experiences with FP+ post them in response to those that posted positive ones. But I don't see the same denial offered, people with negative experiences don't say its not -possible- to have good experiences. But that doesn't seem cut both ways, people who like FP+, or just defend WDW, outright deny the experiences of those with negative experiences or view points of the system. How many people have you seen posted on these boards that its only 5 or 6 people on these boards that don't like FP+ ? (dozens of times) How many times have people posted that its only people who haven't experienced FP+ that are complaining about it? (dozens of times) How many times have people said that unless they try it people have no right to comment negatively about it? (dozens of times) How many unique individuals have now piped in, just on this thread alone even, with negative experiences ? Was it the "usual 5 or 6" nope, because I see them all here and its other people that are chiming in. But we will still be told its only 5 or 6 people on the boards that don't like FP+, probably in the next thread about how well FP+ worked for someone.
Now ask yourself, the opposite, how many times have you seen someone post its only a few people here on the Disboards that like FP+ ??? How many times have you seen someone post that its only people who haven't tried FP+ that like it ? How many times have you seen someone post you have no right to comment positively on it unless you have tried it ? I count none to all of those.
