(I really enjoy the discussion here, thanks for all the participants

)
Sometimes, I call them "Canon- belt Trekkies", but I have great respect to fans who care about canon. To talk about canon, you have to know the canon and it takes to much time, requires to much personal engagements. Discussions between canon followers and the revisionists (

) remember me the fights between ASOIAF readers and GoT fans. I think both sides love passionately enough their object of desire in their own ways. It is something about personal identification and the art of reflection it. It is not Trek specific thing, it should be from the very beginning, even before it became so popular. Cain and Abel could talk about it, I assume.
If we accept the theory that sci-fi or fantasy literature/media products are our modern mythology, we can better understand association of religion, fanatics, reformers, prophets, etc. So far we know, even ancient Egyptian, Greek, Indian, Babylon societies have some variations of their myths. So, why shouldn't we have?
I am fine with infinite parallel realities, so far they keep being logical within their arcs. So, I can also live with craziest fanfics, so far they don't break the frames of their own defined universe. (Well, I am not so tolerant for the novels, excepts AU novels, they do not have art freedom to totally redefine/deny/ignore characters or events whom/ which we know from the shows, imho. I don't mean altering them or writing the missing scenes.)
For me, everything about hope, voyage of being human and even painfully stories about them are canon. Cheap emotional dramas, violation in the name of sensation, cruelty without reason, no where going dead ends, arrogance and superficiality as superiority, all these sort of things are not canon.
