I'm reminded of a scene in a "Star Trek: Deep Space Nine" episode called "Explorers."
Commander Sisko (a space station commander)
is flying a solar-sail powered lightship between two alien star systems, with his son, Jake, an aspiring writer.
Jake has asked his father to critique a story he wrote about a Maquis resistance fighter. Sisko says he likes it, but...
"In some places, you're writing about things you haven't actually experienced...at least I hope you haven't. Unless you've run off and joined the Maquis without telling me."
I am flabbergasted that the TV writer could put that kind of criticism in that character's mouth.
Of all people, a TV writer writing about flying a lightship between alien star systems should appreciate that "write what you know" does not mean "limit your writing to those things you have personally experienced."
