Honestly, the only way I can see it working is if it is clearly indicated as rant and if there are, I guess, definitions for what that entails (god help me, I seriously am turning Ti ). What I mean is, if you want to rant about something and find support, acceptance and a listening ear, you should be able to do so in a safe zone with people understanding that. That also means you forfeit the right of actually investigating that claim, experience, or rant as an objective truth. You can do that later - many people seem to go through a process of first purging, then feeling understood, and because of that being able to understand the other side as well and then have a need to debate in what way this takes place and why, so it is a natural progression. At that point, one could start a new thread, once one is ready for such a place. Once you go to phase two, it is best to use curiosity and detachment and an open mind to research it, to keep miscommunication, escalation and heated arguments flying everywhere - in other words, there the safe haven will not extend in order to prevent platforming and spreading personal opinions as truths.
Now...the thing Im not quite sure about is if FeTi users actually separate those two processes in their head. If this is one big process for them, due to how Fe works. Which would make it harder for them to recognise which stage they are in, making it harder to label things. And for that matter, which might be detrimental to how they solve things, so I need more data on that to really see how to address that
As for practical application - just report someone who steps out of the bounds of the thread. In the rant section - don't post unless you are willing to help the OP out with what they need - a different yet empathetic response, an anecdote that relates so they don't feel alone, a gripe session of your own on that topic. Also don't post anything that starts a hypothesis on whether or not this is true for the general populace - keep it to your personal situation only - no pushing agendas and conclusions, based on this. Those could I suppose get dumped into a second thread to examine the truth of it but because they are often a clash of strong emotions and truth building, they tend to be a toxic component to any thread so I'd say they're better off being called 'Off Topic' until the poster is truly ready and decides on his own to take part in the more analytical thread themselves.
The same thing would be true for the other type of thread: griping could be moved to a rant thread, while griping that masks as truth platforming goes 'Off topic' to keep the debate on track and geared towards what the thread was meant for.
Frankly, I'm not sure how enforceable that would be though, and at some point this stuff does become a judgement call.
And then there is the question: do we want to hyper-organise that way - sure, it would improve thread quality and create safe havens for both emotional support and intellectual discourse. But we're a forum of people that hangs out here in their free time - not professionals. And the actual learning process of this for each newb might be...taxing, as not everyone naturally realises when they are ranting and when they are discussing something in a more detached way. At the same time, I think it could significantly help people discern between T and F situations, and when what is called for, immensely, which would be right up our alley, not to mention leave space for Ti and Fi to putter around without being clobbered by their extraverted cousins, who have their own sandbox to play in.
So, how far do we want to take this? I honestly don't see how else you're going to avoid these kind of train wrecks, but then many people seem to enjoy that kind of drama. So perhaps a poll on whether or not this would work, is in order.
You keep your paws of my art, you!
