Okay, now that I feel you're taking things seriously, I will respond in kind.
Right. Hence the differences between the spoken register(s) and several written registers. This is an online discussion forum, and we're both writing in a casual register, much as we'd speak. As someone mentioned in the other forum, first-person narration is in a more casual register as well, and can also have sentence fragments and break other rules. So all you're saying is right.
My being belittling (for which I apologize) was not because you correctly pointed out that sometimes you can break the rules. It's because you were vague about it, and implied that it meant these rules were irrelevant or not useful. Or that they should simply be ignored.
Quite the opposite -- when publishing (which is what I want this forum to be about), these rules are very relevant. Even the outdated ones like who vs. whom. Any decent editor will know exactly what register you're in at any given moment, and when it's appropriate to be conservative and use "whom" correctly. So knowing exactly when to ignore some or all of the rules is key. Your assertion that they can just be ignored whenever you feel like it is simply chaos.
Well, that doesn't follow for me. Hmm. Other examples perhaps. The law is confusing and should therefore be flouted? No. Proper laboratory procedure is confusing and should therefore be ignored? Nope. Pre-flight equipment checklists are confusing and should be skipped? Hmmm. I can't think of any case where having a confusing set of rules is reason to ignore them....I oversimplifed and didn't check. That wasn't bafflegab - it was arrogant laziness. But my mistake makes my case for me: English grammar can be confusing, and for that reason the rules deserve to be flouted.
So if that's the connection I've been missing in your argument, I think I'll choose to just disagree right there. To the contrary, the service an editor provides to a writer and a publisher is a fine knowledge of when each rule applies and when it may be broken. That distinction would serve us aspiring writers here in the forum, too.
You're oversimplifying again. What I objected to was dismissing the rules because they are both changing and fuzzy at the edges. ALL matters of human language are constantly changing and fuzzy at the edges. In fact it goes much farther than language. You could substitute "rules of civilized behavior" or "rules of civil law" and still be correct to say they're constantly changing and fuzzy at the edges. But I wouldn't suggest flouting them.These aren't questions on the "fringe" - you object to those (why?).
With that understood, I'm not trying to lead a forum about "everyone all the time". (my emphasis above) I'm trying to lead a forum about "how to write so a publisher will want to publish you". And in that case, those rules are darned important. Your observations on how they don't bind everyone at all times are correct, but out of place here.My point isn't that there are no rules, or that they are all useless - that's just you belittling me again. It's just that the rules aren't binding on everyone all the time.
But do it outside your manuscripts, if you please!If you think you can say something better by breaking the rules, go for it.
