I say "attempts" because partway through the article, it essentially shifts the spotlight from heightism, to how short men react to heightism. Starting from here:
"Insecurity generally manifests in oversensitivity to insult (which may contribute to the stereotype of short men as angry, resentful, over-compensating Napoleons.)"
The article then goes on to give various examples of short men who cope with heightism in their own ways.
That's okay and all, but if one looks at The Guardian's articles about fat shaming (of which there are many), the focus is usually only on the prejudice itself. Do a ctrl+f search for words like "insecurity" on their articles about weight, and you'd be hard-pressed to find a single hit. Why? Because the word "insecure" is inherently negative, and makes it seem like the problem is with the person on the receiving end of the stigma. Mainstream websites avoid using such phrases for issues like body shaming, because they don't want readers to think it's the fat person's mentality that's the problem.
There's this part as well:
"As to whether or not short men really require kudos just for being secure … well, it depends on your perspective."
Whatever your perspective is, good luck finding the same line of questioning in mainstream articles about fat women. The message I've gotten from those, is that you're a bigot if you don't automatically praise females for being proud of the bodies. People basically have no choice nowadays but to pat women on the back over body positivity, or else feminists will show up to teach everyone a lesson. Less double standards here would be nice.
The existence of The Guardian's article about height shows how far we've come, and how far we have yet to go in terms of both quantity and quality. On one hand, it's nice that a mainstream website has an article about heightism at all. On the other, it's interesting how many more posts there are about weight than height. The way the topics are discussed is also worth noting. When it comes to weight, the responsibility to behave is placed entirely on how everyone else views overweight people. But when it comes to height, we start talking about how short men should view themselves. It's ironic how The Guardian's height article talks about "toxic masculinity," because the idea of men manning up while women are catered to is a classic gender dynamic. We're getting somewhere though, there's no doubt about that, and a lot of short guys are grateful to get any scraps at all from these publications. I still recall being told to stop discussing heightism years ago because it'd never get any recognition.
