The unfortunate fact is that 'cute & cuddly' lies in the imagination, often driven by visual stimuli. Seals, often considered right up there in the heirarchy of 'cute & cuddly,' are pretty ill-tempered in real life. Sure, they LOOK cute, but that's in the eye of the beholder.
Most of us would rule snakes off this list (even if we're not herpetologically phobic), but not all. How would you fare taking an Emotional Support Pit Viper onto a plane?
This feels like political correctness carried to a ridiculous extreme. It also triumphs the right of the few over the safety and comfort of the majority.
Reminds me of the story about classical cellist Lynn Harrell. When traveling for a concert, he bought a second seat for his mega-bucks cello. Many musicians, of all stripes, do this so (a.) their instrument gets there when they do, and (b.) it arrives in the same number of pieces as when it started (Baggage handlers evidently have tin ears, for
any kind of music). Harrell, who racked up frequent flyer miles galore, registered his cello by name for Delta's Frequent Flyer program, as well as his own name and separate account. After all, Harrell paid, often at premium prices, for the cello's right to a seat next to him. In 2012, Delta denied that claim, took back the cello's mileage AND Harrell's, and banned him for life (Wikipedia attests!). Delta has the right to set its own rules for its Frequent Flyer program, and it also has the inalienable right to be petty and stupid about it.
People name their pets. Would Delta's approach apply to an Emotional Support Animal? Some lawyer somewhere is just waiting...
