On a nitpicky note:
As a Klingon-speaker, I'd like to wipe out a lot of the bad grammar.
A lot of the Klingon dialogue heard in Star Trek is really just gibberish, and I don't really mind that because I can just chalk that up to linguistic diversity; it makes perfect sense for a vast and ancient empire to house more than one language.
However, I'm annoyed by lines that are clearly intended to be in
tlhIngan Hol, but were clearly written by somebody with no real understanding of the language; those are really difficult to retcon, so I end up removing them from my headcanon.
An infamous example comes from Worf's
R'uustai with Jeremy Aster, during which he says
SoS jIH batlh SoH. Translating the words one by one, you get "Mother I honor you.", but when you take the grammar into consideration, it means "I'm a mother. You are honor." or "You are the honor of mother's monitor."
On a less nitpicky note:
I'd like to remove many of the more patriarchal elements of Klingon culture. Most importantly, I'd like to go into the episode DS9: "
The House of Quark" and remove the whole thing about women needing special dispensation to serve on the Klingon High Council.
This is not because I feel that the Klingon Empire needs to be perfectly egalitarian and live up to our 21st century human view of a perfect society. In fact, I'm all in favor of them being specist, colonialist aristocrats who are all about conquest and survival of the fittest.
The reason I wish they were less patriarchal is because I feel that it feeds into an arbitrary and
human view of gender roles. Klingon culture is big on warfare, violence and tests of endurance, with a side of getting drunk, singing songs and breaking stuff.
We sort of expect such a culture to favor men, because in many human cultures these are regarded as typically masculine traits. However, Klingons are
not human, and therefore their view of masculinity and femininity need not match ours.
It would be nice to have show off a stereotypically macho culture in which men and women participate equally, not because the Klingons take a particularly active interest in social equality, but simply because the idea of excluding women has ever really occurred to them. It would be one way in which Star Trek could highlight how arbitrary many of our preconceptions about gender are.
Y'know, kind of like TNG: "Angel One". But hopefully less awful.
