Butches are always sexually aggressive and feral, and in paranormal fantasy they are angry, brutish, impoverished or straight up have animal characteristics. They are usually women of color, with dark hair and dark skin, and can only ever be werewolves or half human hybrids. Femmes are delicate, petite, submissive, more emotionally intelligent and likely to be vampires, faeries, princesses or more such attractive archetypes. they will always be light skinned, if not white, and with preferably blonde or lighter hair and features.
Even with the rise of gl webtoons and visual media, the flirty, sexually dominant one is always dark haired. the innocent wide eyed one is always light haired, and/or fairer. We have ships in media where according to fans the white person by virtue of their light skin becomes more feminine, dandyish and "maternal" (Lestat, Madeline) while the person of color is the "dad" or the butch (Claudia, Louis).
Hell, this isn't even exclusive to racial stereotyping in queer ships, interracial ships with a woman of color and a white man literally have been repackaged into girlboss x malewife trope, an easy excuse to portray the woman as sexually aggressive, brazen and hotheaded, and her sweet white husband as a golden retriever (Luka and Hyuna from Alien Stage come to mind). It is a wild combination of gender essentialism and racism.
