I thought the argument against "Be fan of the PCs" etc wasn't an argument against pithy phrasing itself, but rather a complaint that this was poor phrasing in the context. That is it might have been an attempt at pithy phrasing, but it failed to be communicative for them. I assume it is these kind of objections you have in mind?
I think "GM is reality" phrasing might be open to the same objection. That doesn't mean pithy phrasing as a concept is bad. It just means that care must be used when using them. Using them in a context where the meaning is likely to be not understood should generally be attempted avoided. Recognising when you are in such a context might be really hard.
Edit: Recognising exactly what a complaint is about might be hard though, especially when it is compounded by someone strongly against the meaning (actual, misunderstood or both) of the phrase. I seem to tend to use most generous interpretation unconsciously when interpreting text - sometimes to the point of not really seeing the right words.
Okay. More than a little frustrating, then, for the very people who took others to task for allegedly unclear phrasing, to then use unclear phrasing, and get persnickety when that unclear phrasing results in apparent holes in their arguments.
One should think that, if an interlocutor has previously expressed that unclear phrasing
from others was bad and meriting criticism or rejection
because it was unclear, they would be more receptive to others pointing out when
their phrasing was unclear and thus bad and meriting some form of criticism (and possibly rejection).
In my education as a teacher I was thought an important distinction between being authoritative and being authoritarian. Being authoritative involves people submitting to what you say due to them recognising that what you say is worth listening to. Being authoritarian involves people submitting to you as you demand it, on pain of some sort of punishment.
I think this distinction might be relevant for this conversation.
Sure.
The way GM power has been described by fans of the "traditional GM" has almost exclusively looked authoritarian. The demand for absolute power. The insistence that there will always be serious issues. The inherent stance of
suspicion about player motives. The consistent rejection of even a little bit of
concern, let alone suspicion, regarding GM motives. The claim that collaboration is the enemy--the GM
must exercise their authority totally individually. And the
frequent emphasis on the use of punishment as the means by which the GM not only can but
must control player behavior.
That is what looks authoritarian, not authoritative. The interest is consistently on punishing any deviation and ensuring absolute compliance--not on respecting others as fellow people who have their own interests and interpretations and desires.
It's vanishingly rare to even
consider whether the "traditional GM" should think about what the players actually think, like, or want. And I know for absolute fact there is at least one participant in this conversation who thinks that doing that is not only bad, it is
actively harmful to any form of play, full stop.
