That's a bit harsh. I don't think anyone is asking you to attend what you feel is their pity party.
You may feel that people are 'downgrading' if they cruise other lines, I don't. Doesn't make me right or wrong. Same goes for you, doesn't make you right or wrong.
Money for us is not tight. I could cruise however I want however I choose not to spend on
DCL for a week what I can spend for two weeks on another ship. That other ship may not have the same family activities/entertainment but from what I have seen and booked it seems to have more. Less attractive ship? Not Disney designed but not less attractive. Lesser service? Don't know yet but I doubt it would be $2000 worth of lesser service.
Some people choose not to sail less than 7 days. For us, we have to drive 26 hours or fly at a high cost so doing this for a 3/4 day cruise is pouring salt in the wound so to speak. Also, while you seem to feel that sailing anytime is okay, for those with children in school it is not always a possibility so that option is not valid for some.
Don't discount others feelings because you don't see the same way. No one has requested or wants your pity. They want to voice their thoughts and feelings which are every bit as valid as yours. I get what your saying but please understand that others don't have to be saying the same thing or else be wrong.
