I consider the first one common sense, because if the facilities exist to do the job on land, and if the construction methods are presumably more efficient to do it that way, then its monumentally stupid to do it in space.
Didn't say you couldn't call it common sense I said doing so doesn't make it a "fact" of how it was "fictionally" done or not done.
The ceremony in the third makes a space construction for Enterprise B cannon because that ceremony is normally performed when the hull is launched but before it is properly fitted out, which was the condition of Enterprise B in the film.
On terrestrial naval ships that is the ceremony. But the B was already constructed at the start of the film so there is no "canon" on how or where it was built just the implication. They could just as easily have built it on the surface, tractored it into space and had it's "launching" ceremony there. It would not contradict one ounce of "canon" if that were the case.
Yes it is fiction, but fiction with a 40 year history, and established laws and rules. Complaining that the creative team for the new movie is completely ignoring these rules after promising that they would not is not pretending.
There is no established anything with regard to the construction of the TOS Enterprise, there is no "canon" to ignore because there is no "canon" on the subject. Point out one "rule" which says all ships are or must be built in space.
I consider your accusations of pretending to be an insult because they lump me into what I view as an extremist category which I am most certainly not in, so either send me your name and address or shut up.
You're arguing about a fictional ship's construction process, not just that but you're upset that people making a movie aren't building it "correctly" and you want to "step outside" because I call discussing the pretend process of building a pretend ship and the pretend rules it functions under pretending. You don't find that at all "extreme".
1. The federation is usually portrayed as operating intelligently. If major apparently superior shipbuilding facilities exist on the surface then doing a TMP type overhaul in space is stupid. Therefore by indicating that such facilities exist the writers of this movie are depicting the federation as being stupid, and violating cannon.

1. Enterprise B. Was not completed as of Generations key systems were not installed
2. While its never explicitly stated that all ships are built in space, the fact remains that over the past 30 years, every time a ship is depicted as being built or receiving a major overhaul, its been in space.
3. The "pretend rules" the world of Star Trek function under are part of what differentiates it from those B-movie type scifis with ships on strings. That's one of the reasons why I am unhappy with them suddenly ignoring the established cannon. I do not consider myself an extremist because it takes something this big to annoy me. I have no problem with them recasting characters or re-writing character biographies altering what the community generally accepted but which was not supported by onscreen cannon. I also recognize that with 40 years worth of scripts, its impossible to keep the cannon entirely straight, and I accept a degree of retconning. That is why I am not an extremist. I only became upset when I read the interview because I view his explanations to be rather insulting to my intelligence. I'm calling you out because you have no problem being insulting and insinuating that my views are more extreme that what they truly are here, but you would probably reconsider face to face.
