Okay, then what about all this?
Have fat women been treated like black people? Make no mistake, body shaming in general is hurtful, but it's interesting how much more politically incorrect it is to talk about weight compared to height. Matt Lewis pointed this out on CNN here:
Speaking of which, did weight disorders exist before they were researched? This is a rhetorical question, of course the answer is yes. The only difference is whether the disorder is acknowledged in the first place. Go to some forum like reddit.com/r/short and one can easily see that many males suffer from body image issues. Where's the concern? While this society harps on about "toxic masculinity," it seems not much has changed, because men are still expected to invincible while women are not.
People outright insult short men all the time, and at best barely anyone cares. At worst, any short guy who has a problem with it is labeled as insecure. When it comes to body shaming, notice how the focus is not on whether women take it on the chin, but rather the spotlight is on the initial rudeness itself. In fact, merely asking about or pointing out a woman's weight is considered rude, let alone mocking it. There's a reason why the WWE announces the men's weights but not the women's. Social conditioning has taught people that saying virtually anything about the obese is bullying, while most things height related are always classified as a joke (I wonder if this feminist and the 300+ who liked her tweet would think the same line about fat or flat women is funny). Spoilers: she wouldn't. It's also interesting how some feminists take out their frustration on men who already aren't respected. Ever notice how these feminists don't use tall handsome guys as their punching bags?
Anyway, when you're told from a young age that simply asking a woman about her weight is a cardinal sin, of course every comment about weight would be viewed as bullying. There can be no malicious intent behind saying something weight related, but it's considered rude regardless. If I'm wrong, then tell me one comment about weight that you can publicly say to a woman's face and have it not be considered rude. On the other hand, you can outright insult a short man, and if he doesn't take it obediently, then the problem is on his end (he has a napoleon complex, he's insecure, etc.).
Update: Apparently, universities also have a 'fat studies' course about the discrimination fat women face.
Update 2: While society is treating fat shaming as a serious issue, here is the kind of presentation heightism gets. It's all a joke to them, even when talking about derogatory stereotypes or the height wage gap.
Update 3: I keep finding more weirdness about how society views height.
Whenever I see women mocked over their traits, be it weight, height, breast size or whatever, there's always a plethora of people rushing to defend them. For example, when 4'11 Ariana Grande was mocked about her size, it sparked outrage. Often we see even 5'7 - 5'8 male stars like Tom Cruise or Kit Harington being mocked about their height. Where's the same reaction?
This is why weightism has a university course while heightism remains a humorous topic. It's not the trait being targeted that matters, it's which gender is being affected. Hypothetically, if women cared about height prejudice rather than fat shaming, would people be defending short women or fat men right now?
