Ulga\Owl is male (mtf), whilst the partner Fox is female (ftm).
Both have written articles for the site and both don't like it known that they are a couple as it reduces the impact of the articles, because it doesn't look like two independent people fighting for trans rights.
Fox wrote an article with so much cognitive dissonance it was unbelievable. Fox worked in a care home for elderly trans patients and one mtf had dementia and couldn't understand why they had a female-resembling body and not their natural male body. But apparently gender dysphoria is innate!
