I don't entirely agree, because we have to go by what actually appeared on the screen, not by what someone's intention was early on that got changed.
"Have to?" No. It's a creative work. We're allowed to analyze it on any level we want. Fiction is not an authoritarian dogma. It's supposed to stimulate our thought and imagination, not restrict them. I see no reason to limit oneself to considering a work of fiction from only one perspective.
If the subject of the conversation is the validity of taking families aboard starships, then I think it's negligent
not to consider the intentions of TNG's creators when they introduced the idea.
If they had intended the entire crew to go into dangerous situations as a matter of routine, then they might not have decided to put families on board. The reason they did make that choice is because they expected that the families would not be taken into combat along with the rest of the crew. You can't understand or fairly judge their creative choice if you don't recognize that they were approaching it from that perspective.
The decision made by later creators to abandon saucer separation, as I said, was forced largely by the practical difficulty of working with the miniature. If that had not been an issue, they might have chosen to continue the practice. Again, it is impossible to fairly assess their choice without considering all the factors that went into it. It's unfair to argue that bringing families on starships was an illogical choice if you willfully refuse to acknowledge the real-world considerations that led to a fundamental mismatch between the creators' original intentions and the final practice of the show. Yes, it's a flaw, but it's a flaw that exists for well-documented reasons.
In the entirety of the Enterprise-D's lifespan that we saw on screen, saucer separation was performed only four times. And in one of those four times, it was actually done so that the saucer could be used as a diversion in combat! It seems clear, then, that either Starfleet or Captain Picard (or both) do not consider it a routine practice to separate, even when there is a good possibility of a combat situation developing.
Picard is a fictional character. The only reason he didn't use saucer separation more is that the writers chose not to let him. And that's because the original writers who came up with saucer separation were replaced, and because it proved too impractical to shoot saucer-sep scenes on a regular basis. It's not something that arose organically from in-story logic, it's something that was artificially forced on the show and characters by real-world factors.
In addition, even if the practice was to separate before going into combat, the truth is that we often see situations where combat is unexpected or unpredictable. You're not always going to have the opportunity to separate the ship. So even if that were standard practice, you are still going to be taking families into combat situations from time to time.
Yes, and you could get killed in traffic driving to work in the morning, or you could get caught in a wildfire or earthquake or toxic gas leak in your own house. No situation is completely free of danger. I've heard this objection raised a thousand times over the past 38 years, and I've always found it disingenuous.
Especially since it's a TV show. Dangerous situations happen because that's what adventure shows are about. Set a Trek series on a planet surface, and that planet will get attacked just as regularly as a starship would.
