If the group-think and witch hunting is as hard on you as you seem to describe, I can assure you there are MANY others in the same position.
So make your own thing.
Why’s that bad? Why are you responsible for expanding the minds and exposing the group-think sheep to new viewpoints? Live in your own rebel communities. Basically like the internet has operated for the last 30 years.
The adventurous among them will venture over when they want.
Maybe. And maybe it's my age showing. But there's one other thing - the modern social media solve for a different problem than the forums and boards of yore: they're all-encompassing, topic-agnostic. They're social, as in, one identity, for everything, with everyone.
Back in the day, topical, isolated cliques were all we had. All the different mailing groups, IRC servers, phpBB boards, etc. were entirely independent of each other. Sure, I may have used the same handle on a bunch of them, but reputation - good or bad, pristine or smeared - did not propagate through the boundaries. Then social media happened, and we got used to having centralized platforms, with a single identity, for all aspects of life. That's the world of Facebook, Twitter, et al. Mastodon is just decentralizing Twitter on a protocol level - it's carrying over the expectation of single identity, of a topic-agnostic, all-encompassing platform.

Because the Internet isn't a niche hobby anymore. It is life. There's no on-line vs. off-line anymore, they're both intertwined in almost everything we do daily. In other words, it's serious. Serious, as in, standing up to worst cases of dishonesty and hatred on some board may suddenly cost you your actual job, and your family a roof over their heads.
People have tried to create more sensible set of community rules on Mastodon. Last I checked, none of those attempts were successful - mostly because anyone who tries or is seen supporting the attempt, gets shot on sight^W^W^Waccused of being hateful racist bigot wanting to harbor literal nazis. There's an inherent asymmetry here; it's the same kind of play as "would someone think of the children", except the society doesn't have antibodies for the former just yet, like it has for the latter.
Mastodon is decentralized at the protocol level. It's the opposite of that at the social level. The mob rule may be "decentralized", but it turns out it still sucks. Cross one extremist and get accused of being a bigot / -ist du jour, and them and their friend will run you out of town. No big deal, you say, you can always switch towns? Except no, because the extremists will follow and denounce you for your "bigotry" / -ism, and threaten to do the same to anyone willing to harbor you, and then no town will want you in, because none of them want to be cut off of everyone else. On the main subnet, it's every instance pointing a gun at every other one - even if most believe the common rules are extreme, no one trusts others enough to challenge them.
The irony is, this is basically rediscovering the lessons of past thousand years of civilization. Mastodon is the digital equivalent of a sea of towns afraid of their own people and other towns alike, due to roving parties of political officers executing criminals and wrongthinkers alike. Somewhere along the way people figured that rule of law, presumption of innocence, due process, proportionality of punishment, civilization, are nice things to have.
Anyway. Been there, done that, tried to enjoy it while pretending there is no problem, until the admin retired the instance. I don't feel like participating again. I'm off both Twitter and Mastodon. As much as I hate corporate ad-poisoned Internet, I do have to grant it that it's the more honest one - people will do bad things to each other in pursuit of ad revenue (or revenue in general), but at least they're not pretending too much. They're not bending their own minds past breaking point to feel OK with delivering mob punishment and signalling allegiance to not become targets themselves.
