Disney is a very positive, up-beat, optimistic place to go. Its a place where goodness triumphs over evil, a place where being good is rewarded and being bad is punished. Where people are the best they can be. (No offense to that famous Army slogan.)
The place reeks (in a good way) of absolute truth and timeless values of right and wrong. Every Disney fanatic I've ever met loves that about things Disney. It renews and recharges them in almost a spiritual way. Its a place that strips away some of the crazyness of our normal lives and allows us to live... temporarily... in a better place. Where people are nicer and more friendly... for the most part.
Some people, as it is written in the Gospel of John, "prefer the darkness to the light" and love evil and hate what is good. For these sad folks, WDW is an intensely uncomfortable place to be, as it reminds them of everything they despise, everything they are not. Please understand I am NOT saying you need to be religious to enjoy Disney. Thats just not the case in my opinion. All you have to do is prefer to be nice rather than to be mean.
Its really pointless to try to convice those who hate WDW to like the place. Unless they have a change of heart about the rest of their lives first.
PS my brother hates WDW... especially Epcot because the "countries" are so fake. Yeah, whats the point in visiting Mexico if you can't get dysentary. Or visit Paris and not be hit on by prostitutes. Or go to Italy and smell the sewage and get in fist fights with emotional Italian men. My brother didn't like New Orleans Square at
Disneyland because it didn't have all the pick-pockets, prostitutes, the stench of rotting garbage and flies. I'll take the Disney version thank you very much.
