4. Claim that newer characters and concepts should dominate the parks

PIXAR is great, yes. Almost everybody loves Toy Story, Monsters, Inc., Finding Nemo and many of the other properties under the PIXAR brand. But to say that just because their properties are popular now they should take over the Disney parks is ludicrous, especially to the longtime fans. A castle featuring Merida from Brave would be cool, sure, but if you keep insisting that she deserves to replace the classic Disney princesses like Cinderella, Snow White or Sleeping Beauty then you’re in for a big debate amongst the people old enough to remember when those films were in their prime.

5. Say that non-Disney properties belong in the parks

It wasn’t until 1987 that Star Tours, the first attraction at a Disney park not based on a Disney property, debuted. And even that retroactively became an official Disney attraction when the Walt Disney Company purchased Lucasfilm for $4 billion in 2012. There are plenty of people still going to Disney World, Disneyland, etc. who remember a time before 1987, when there was essentially nothing at the parks that wasn’t Disney-based. So if any people try to argue that characters and settings from Avatar deserve to be at Disney theme parks like the Animal Kingdom as much as the Mickey Mouse family with Camp Minnie-Mickey, they’re probably in for a rough time.

6. Declare that Universal Studios is better

A hardcore Disney theme parks fan is almost definitely going to end up at odds with a similarly intense Universal Studios fan. The rivalry between the two theme park empires is an epic one, and with Universal’s improvement in the form of The Wizarding World of Harry Potter, the competition has become even more fierce. Any hardcore Disney fan will feel or inflict pain when someone has the audacity to insist that the Universal Studios theme park experience trumps that of the one put on by the Walt Disney Company. There’s some stiff competition, but that might be the number one of these ways to irritate longtime Disney fans.
