I think he means that for the most part we have agreed to and accepted the canon (even if we don't like the presentation of parts of it) so for someone frankly unknown to come in and trounce on it is pretty disrespectful towards everything Wing Commander stands for, which includes the fan community.
I'm not sure if you're referring to me, but if you are, I would say a few words.
At no point did I "trounce on the canon". This thread started with someone posting questions about inconsistencies that bothered them, and it caught my eye because many of the same inconsistencies have occurred to me. Some other poster said something to the effect of he didn't let the differences bother him because he enjoyed the movie separately from the games, and I originally posted to agree with him, as I do much the same thing. It was only after I was then attacked that I fired off a lengthy but hurried post which, I'll admit, probably came off somewhat more hostilely than I intended. I have never made claims that the canon is wrong because it doesn't fit my personal vision, just that apparent inconsistencies (which may well be explained away by resources that I have not read) do not bother me because I keep them separate in my mind.
I admitted that I have never read any of the novels, nor seen the animated series. For that matter, I have never even played Academy or Armada (I own them but have yet to get them to work on modern computers). I have loved Wing Commander passionately for years, and one of these days I will get around to trying the novels, and maybe getting Armada working. When I do so, if they fill in gaps that make some of the inconsistencies that bother me go away, then I'm sure the movie and the games will come together in my mind; if they do not, I'll continue with my life and continue to enjoy the games as some of the greatest games ever written and the movie as something fun to rent when I have nothing better to do, and I'll continue to not stress about inconsistencies. I fail to see how this attitude "trounces on the canon" or "is disrespectful to everything Wing Commander stands for". It's a game, people. A wonder, beloved game that was ahead of its time and that lives on today, but not political leader or a religious belief or a martyr or something that I sully the image of by even suggesting that inconsistencies between its various components exist.
And of course the notion of "personal canon" exists. None of us came into existence knowing everything there was to know about Wing Commander instantaneously (well, maybe BanditLOAF did, but anyway...) There was always a time when there was some hole in our knowledge. As we were discussing earlier, since there is a "Story still to be told category", there are obviously still some holes to be filled for everyone. Of course we all, in the absence of further information, imagine stories or scenarios that might fill in these holes. People did that with Star Wars for years before the prequels came out (and some people still do, ignoring the prequels). As we play additional games or read novels that we manage to find, naturally some of our imagined stories are proved to be wrong, and we replace our imaginings with "canon". However, our own fancies continue to fill in all the holes that remain. Since everyone has been exposed to different amounts of the story, everyone's preception of the games is slightly different, which is what leads to interesting debates and insights.
For example, I know that of the original seven Claw pilots (after Bossman died) in WC 1, only Spirit, Angel, Maniac, and Paladin survived till WC2 (and apparently Hunter, as has been discussed). I always imagined that the reason why they survived is that they, like Blair, probably were out on patrol, while Knight and Iceman probably had flown the earlier shift and were in their beds or in the bar when the Claw went up. Then Prophecy came along and told us more about Iceman, and between that and what folks here have told me, I have found out that Iceman survived the Claw, but the exact circumstances of his death, and perhaps Blair's pickup, are still unknown. So now my view of the universe has evolved, and my imagined stories have been replaced. I still wonder and imagine how it happened, and how Knight met his end. But the implication of some of the posters here is that by even imagining things that have not been spelled out explicitly is somehow heretical because I'm creating my own personal canon...
And as to "someone unknown"--I have been visiting this site for years. I rarely post, and when I do I often do not bother to log in. Still, I fail to see how that is relevant. If I had posted every day for the last five years, would my opinions somehow be more valid or better?
