Wraith fans sometimes try to set their OC Wraith apart by adding to their OC world-building. But, the majority of the so-called “alien” additions are actually customs that global cultures have had for thousands of years (or used to have, before being steamrolled over by Western colonialism and cis-hetero-masculine-dominant religions).
Inclusiveness for non-binary people, community bathing, not sleeping on Western-style beds, community child-raising, non-nuclear families, and community sleeping, for example, are all parts of Earth human cultures.
Even in Legacyverse, the games, fashion, and names are found in a mashup of the ways of other cultures, both past and present. The words “zenana,” “blade,” and “Consort,” for instance, were taken from court life, Eastern and Western, but with the Wraith Queen being the court leader, rather than a human king. What was once old is now new again.
Similarly, on-screen details about Wraith, such as matriarchy, tribal style tattoo art, males having long hair and wearing nail lacquer too, chanting, and martial arts have existed globally on Earth for thousands of years.
Recognizing these traditions, here or on other planets is great. But, to label any non-Western traditions as “alien” is to erase global Earth cultures and to mythologize the white Western way as the only human way.
Also, humans can and should have what Wraith do too: environmentally-friendly, lab-grown items and respect for the environment. Some of that exists to us now, from emerging cruelty-free, lab-grown and cultured materials, such as from pineapple leaves, coconut water, kombucha, and mushrooms.
Within SGA, the White-cis-hetero-masculine-ableist-colonialist way is what is represented to the Pegasus galaxy’s citizens, though the military’s presence. At least the Goa’uld in SG1 had a better picture of humanity as a whole, by their posing as various global and multicultural deities and figures.
When it all boils down, there is no way around that we are all more similar than different.
(((Note: Mistaking global traditions, past or present, for alien is seen more so from comments on Wraith fanfics than in the fanfics themselves. Often, the authors are very well-versed in history and know exactly what they are using as building blocks, even disclosing them and expounding on them when readers do ask.)))
