this is not a solution for untangling disagreement.
i've not seen any conflict solved by doing this
At some point you have to start addressing the people who are actively trying to make others' lives worse through harassment, discrimination, and violence.
If doxing and criticizing people for their beliefs and practices is not okay for the right to do, then it's not okay for the left to do either.
Small correction, this doesn't happen on Kiwi Farms. Kiwi Farms is focused on discussing much more mundane, public drama. Just interactions between people, mostly on public social media like Twitter, Youtube and others. Things like hacking, private financial information, DDoSing, swatting, are all heavily policed on Kiwi Farms. Additionally, directly interacting with the subject of a thread on Kiwi Farms is also bannable.
Their ethos is watching monkeys in the zoo, not going out and poking them themselves.
There's actual shady forums out there that do those illegal things, generally hosted in foreign countries or behind Tor.
But before you do, you should make sure that a crime was actually committed, and mere criticism, or sharing information you posted yourself, or sharing information which can be found via the 21st-century equivalent of a phone book, is not criminal in the United States. And that's usually what a "dox" is; very rarely does it involve hacking into government databases or something like that.
"Beliefs and practices" is, again, leaving aside the "who swung first" aspect. Have all the beliefs and practices you want that don't involve harassing others. If your beliefs are homophobic/transphobic/racist/sexist/etc and you choose to then "practice" those beliefs by harassing people you don't like, you swung first and you shouldn't be surprised if society looks down on you for it.
A great deal of what gets called "cancel culture" is people reacting to someone behaving in a way that harms others, including but not limited to...
- Discrimination (gender, orientation, religion, race, whatever) - Harassment - Threats, ranging from the subtle to the overt - Actual violence
Quite often, the targets of this behavior have done nothing beyond exist and be honest about who they are and how they see themselves. Their harassers swung first.
To take your porn example (I too am old enough to remember the 90s), the moral majority was swinging first. They were offended by porn, but no one was forcing them to consume it. No one was threatening or harassing them.
Maybe the right wing (which is where the moral majority centered as well) should consider why they keep swinging first instead of why sometimes people swing back.
