The question here was not which one is better or worse, or which one is right or wrong, or even what views, in the past, you have found to be inherently aggressive because certain unidentified people didn't preface their statements as I personally suggest they should have. It's not about the specific chips on our specific shoulders.
The question you posed at the top of the thread was "Can the RPG Theory well be unpoisoned?" If we are to answer that question we have to ask ourselves how to do that for everyone who comes to it in good faith (with the obvious caveats that bigotry of any kind is not tolerated). It's not about making sure that your viewpoint is accepted as truth. It's about making sure that people with different viewpoints feel comfortable and show one another courtesy, respect, and understanding.
I am not implying that anyone has to actually buy into my philosophy (and I am not a strict relativist, by the way - I simply think that if certain rules or systems work *for* someone, even if that's just one person, then they have a valid reason to exist, and that most configurations can work *for* either specific people or a specific purpose). My point was that even if you privately think someone is dead wrong, let them, as you put it, do the work they think they can do in peace, without being screamed at by anyone.
Nobody should be trying to keep someone from doing what they want to do if what they want to do isn't hurting anybody, and that also means that, when you're out there talking theory, it might help to avoid "yucking their yum," so to speak.
And let's be realistic, as passionate as we might get about the topic, game design really isn't a life or death affair - we can afford to let other people hold vastly different ideas about the process of design because at the end of the day we aren't commanding troops, building jet engines, or developing vaccines. What we do has value, but it's not something that warrants vitriol.
Again, what I am speaking to right now has nothing to do with actual game design, because this topic was not about game design but rather about how we discuss it. This is not about what methodologies, systems, approaches, or "factions" are right or wrong. This is about making sure that when people do talk about those thing, they can do so without their blood pressure going up (because that can cause actual harm).
And to that effect, I am more than happy to make some definitive statements. Like I said, not a strict relativist. I try to be pragmatic.
I feel that in some cases, hard lines must be drawn so that people don't get hurt. How one comports oneself among one's peers is subject to that principle for me. I am not interested in creating needless anxiety for people just because someone thinks dice pool resolution mechanics are inherently better than reading the shapes in the clouds. It's not worth it. So I am more than happy to make a strong statement on that: let them do their work in peace and if you can't simply respect one another's approaches and engage without prescribing, do not engage.
I also feel that in some cases, drawing a hard line will in fact be counterproductive and will result in more anxiety. The example above works for this purpose too, as it contains both scenarios in one. It's not worth insisting that dice pool mechanics are inherently better, even if you think they are. The way we talk to each other has the potential to do harm, and has to be approached with that in mind. If we want to avoid toxicity, we have to draw hard lines, establish certain norms. The way we design games, on the other hand, is, frankly, our own business at the end of the day. It isn't worth it to cross the lines or violate the norms established in the previous "step" for the sake of dice pools. Let the other person do the work they think they can do in peace.
This topic, I thought, was about exchanging ideas about theory in a way that doesn't lead people to dread reading the replies to a post they made in good faith, and your question was "can we do that."
I think we probably can. Whether or not we will is a different matter entirely.
In any case, I'm probably going to retire myself from this particular thread going forward. When I am into a topic and passionate about it, it can be a bit of a double edged sword. I just can't keep myself from writing novellas every time. I think at this point I've articulated what I wanted to and will just end up going in a circle if I keep at it.
Everything having been said, I really appreciate what everyone's brought to this discussion so far, and would like to thank the OP for starting it up, even if we seem to disagree on certain points.
