A lot of overlap in hair loss and heightism communities

Here's the deal with what you're pointing out here. All forms of discrimination and unfair judgment operate by using the same mechanisms. You take a group and put them in a no-win-situation where you drum-up negative stereotypes about them , and then, when they try to offer a rebuttal, you tell them that they're reaffirming all of the negative claims you're making about them.(aka, you Kafka Trap them) In addition, members of the status-quo ban together to ensure that they have one another's backs when the marginalized person gets "out of line," and they work together to put them back in line. Most members of said marginalized group will be so accustomed to living under this no-win-situation that they turn to individualistic measures to try to minimize the effects of the discrimination. This is where your Uncle Toms, Garmins, little tough guys, heightism-deniers etc come into the picture. Basically, other than the fact that the other isms get addressed and aren't currently celebrated by society as a whole, everything else we talk about in-regard to heightism on this forum exists in the realm of all isms. This is why modern wokelings are so transparent in their hypocritical hatred of short men. Heightism uses the same mechanics as the forms of discrimination these wokelings crow about, yet, they play dumb when they're using these very mechanisms against short men. They'll use every tactic in existence to mock and dismiss short men, and they'll use discriminatory mechanisms to scold us if we try to defend ourselves against their actions. In addition, while they're discriminating against us, they'll get foaming-at-the-mouth angry if they read an anonymous anecdote written by someone with an anime profile picture who reports an alleged act of discrimination toward someone from a protected group. Their psyche is the land of two very different extremes when you look at the way they treat short men versus how they jump to action to defend hypothetical members of protected groups. They're both chomping at the bit to discriminate against real short men, while they'll stomp a hole in the carpet to defend even a hypothetical person from a protected class.

On the subject of other isms, learning about those isms is part of how I came to know heightism exists. Before I even knew of the word heightism, I learned about how all of the popular isms such as racism, sexism, etc worked, and as I learned about the mechanics of those forms of discrimination, I had an "A-Ha" moment where I realized how familiar the various things that happened within those isms were to me personally. An example of what I'm talking about is how feminists will tell you that a quiet woman is perceived as weak, and an outspoken women is considered a bitch. This is absolutely no different than how a timid short guy is considered weak and unmasculine, but an outspoken short man is overcompensating and has a Napoleon Complex. I heard black people talk about how no matter what they do in life, no matter how much they accomplish, or how competent they are, people will always find ways to remind them that they're black. I definitely related to that too because as a short man, people seem to live with a terror that I'm at some point going to forget I'm short, thus, they have to constantly remind me in numerous ways, especially when I achieve a major(or even minor) accomplishment. They don't want me being too proud of my accomplishments or sure in my abilities, thus, I have to be constantly reminded that I'm "still short." These are what sociologists refer to as "microaggressions," but I like how Joe often refers to them as "arbitrary indignities." Anyway, these are just a few examples of the mechanics of other isms that I relate to as a short man, but after learning about the tactics used in the forms of discrimination that society cares to address, I started understanding that I was also the recipient of discriminatory actions.

Where things went south is when I would articulate how I related to people in these other groups because of how I was treated on account of my height. I don't even have to tell you that this did not work out well for me. I was mocked, shouted at, ganged up on, quickly dismissed, and put back in my place immediately when I would suggest that being short allowed me to relate to people who were from other disenfranchised groups. The sudden bond people would have when it came time to put me in my place was a complete eye-opener. They took the utmost delight in working together to shut me down, and this really drove me to the awakening I needed to understand how deeply ingrained heightism is in society. When I would tell people from other groups that I related to them on account of my height, I wasn't trying to lessen the support the other groups received, and as a matter of fact, my self-disclosure was just an example of me trying to tell them I was in their corner. As a young buck, I was a bit befuddled when these people took such a hard-line stance against allowing me to ally with them, but you live and learn, and at-least I can say I made a good faith effort to try to ally with people from other groups before writing them off. Now, I know definitively that no one is going to be in our corner. At a bare minimum, at-least it is now on the record that I extended my hand across the aisle numerous times and other groups smacked it away repeatedly. We've never closed the door for people to ally with us, thus, the longer they refuse to join us in our corner, the more evidence we have of their hypocrisy.

As to the original topic though, yes, mockery of baldness probably does hold some parallels that mirror the things short men encounter as far as heightism goes, including the denial platitudes. Also, baldness and shortness are issues that affect men disproportionately, thus, both will always be looked upon as comic relief, especially in the media. For the same reason that breast cancer is taken much more seriously than testicular cancer, shortness and baldness in males will always be the target of derision, scoffing, and mocking, and men who belong to those groups will continue to deny that any of this exists. They do this out of fear, as a damage control mechanism, and as a means to beg for scraps from those who hold power over them.
