A psychiatrically-minded (pun unintended) reader might infer from my frequent rants about the Mahou Shoujo Lyrical Nanoha Original Character creation community that I have some sort of grudge against certain people. I don't remember if I've said it before, but to be safe, I shall reiterate: I am but one side of this multifaceted story. Others may have different viewpoints, and several are probably more convincing than mine.
In short, the obvious: don't take just my word for it.
I don't actually have any grudge per se, at least consciously. My primary distaste is with the habit of forceful arguments, using loaded words and condescending dismissals; it gives me an actual physical headache, possibly through some psychosomatic influence. There is the unnerving feeling that the debate is not being conducted logically; the participants are not playing fair.
This also explains my decreased presence in the AnimeSuki thread. The rules of the forum state that there is one, and only one, thread per topic, and "Original Characters In The Nanoha-verse" counts as one topic. So if I encounter friction with other regulars of that thread, or at least their debating technique, there's not exactly anywhere else I can go other than "away".
I also have no illusions that this post will make me in any way popular with the community. So it goes.
In such an emotionally-charged situation, possibly no other collection of three words can cause as much ill feeling as "suspension of disbelief". We all know that the Nanoha-verse is not a place with especially stringent physical laws, at least as we understand them in Real Life. While endless entertainment can be had in speculating whether characters would act in a way claimed by a fanfic, human behaviour being somewhat unpredictable, natural laws are supposed to be marginally consistent. (On a macro level, as a rule of thumb, and several other disclaimers to satisfy the nitpicky out there.) The Nanoha-verse, however, asks one question first and foremost: is it cool?
