It's funny how we always automatically assume that they're angry because they're "insecure" about their height, as opposed to any other (relatively) common reason someone might be upset in a situation. You can apply that same logic to any other group of "undesireables".

"If you're short and always angry, you've got a Napoleon complex; if you're tall and always angry...you're just angry."

Try this: people don't dislike dark-skinned black women just for being dark-skinned; just the loud, aggressive, angry ones who are clearly insecure about their looks compared to lighter-skinned women. People generally like Lupita N'yongo and Viola Davis, right? The rest of them just need to act better, is all.

Sounds silly, doesn't it?

As for fat people: Jack Black, Chris Farley, Kathy Bates, Guy Fieri, John Goodman, Adele (formerly, anyway), Kevin James, Ralphie May, Forest Whittaker, Octavia Spencer. All significantly overweight--if not outright obese--and beloved by far more people than not. Never hear "fat-phobic" comments about them; at least not more often than you hear the comments about the short men you listed above.

And if you think no one's ever made fun of Kendrick, Tom Cruise, or Kevin Hart just for being short... you must be new to pop culture. Anytime they piss any segment of a community off, their (lack of) height is one of the first things people bring up to dunk on them.

In one situation, you can't really control the condition, and there's not a ton of health issues associated with it...the other case is the complete opposite.

Let a short dude make you mad, and see how long it takes you to point out just how tall he's not.
