Dealing with super fans on issues is annoying, but ignorable. Dealing with super users is an unavoidable reality that all internet users face at some point or another. You've likely met plenty of them. You have Linux users who swear all Windows users are sheep to be data-harvested (as if Microsoft actually cares about our individual lives enough to harvest our data). You have Windows users who claim that all other operating systems are bad and featureless and underdeveloped (despite many of them dating back for decades). You've got Vim and Emacs users that argue about the efficiency v/ customization of each editor. You've got social media denizens who "only use twitter" or "only use instagram" as if life is a one-dimensional social construct.
But it is unavoidable. If you ask an iPhone carrier to recommend a good android, they'll always tell you to buy an iPhone. Same in reverse. You can never trust a super user to give you a real opinion on something that goes against their super usage. In a world where so many people are super users, you're almost never guaranteed to get a real opinion. I'll use a few of my examples here in tandem with real experience examples:
Twitter users have a fondness for talking about how horrible and toxic Twitter is. From my personal experience, that's really only true for a fraction of my use-time. The other time is spent saying things that nobody actually gives a shit about. The real level of toxicity on Twitter depends on how toxic you are to other people. If you're constantly shitting on others, then you can expect others to constantly shit on you. If you never shit on anybody, you can expect to get shit on by the outliers who believe that everybody everywhere has to be toxic or they're weak. It's a smaller overall margin in comparison. I mean, sure; if you piss off everybody then maybe twitter is a toxic wasteland.
Console vs console vs PC. Time old tale. Gamers can't just be satisfied with playing a good game. They need more pixels that they can barely see, or extra imperceivable frames because they (illogically) believe that more FPS means lower latency. Console users will tell you that a PC does all of this shit that they don't want. PC users will tell you that console users are just using the least efficient method. I'm a fan of the idea that they all have benefits. Consoles are more convenient than PC, but PC is more expandable than console. You can do more with a PC, but in what world does that relate to just playing a video game?
Unity/Unreal/Godot/GM devs will always tell you %100 of the time that their particular engine of choice is the definitive method for making video games. Along that chain of idiocy, they often forget that somebody else built and coded those engines. They forget that real programmers actually develop software. They're so accustomed to the visual editors and interfaces of engine environments that they never actually learn to code, or they learn how to write specific code without ever learning what it does. It's not optimal, but you can program games with just notepad and the command line if you want to. Engine super users are engine super users because they didn't believe in learning any programming beyond their rudimentary understanding. What, did you think it was impossible to make that thing happen with that engine? Maybe it's because you can't write code probably.
Windows/Linux is better than the other. What a weird string of logic. I've used too many linux distros to count, and I've had windows forever. The real effective difference? Not much, honestly. Some linux distros can be hard to set up, and there is the reality that Linux is modular and more customizable. But how exactly does that appeal to the common end user? It really doesn't. They don't want overcomplexity for minor improvements that they won't use and don't understand. They just want a machine that works. A good Linux Mint laptop will do the same stuff that a windows notebook will do. A mac will do nothing because apple is garbage. There's no real divide between operating systems aside from what you want to use it for, and how much you want to change about it. Even here where I insult macintosh; there's still the argument to be made that the parts that work are no different than any other OS.
