Nope, different nerd culture entirely. Seriously, they have their own conventions, instead of fursuits they do custom silicone tails and train to swim in them, have contests and pagents and things. There’s basically no overlap between the two communities. Scaleys are folk in the fursuit community who do dragon and lizard personas.
I have odd connections. Being in the film industry I have friends through props depts who do furry cons and one of my coworkers does underwater photography for people in the Mermaid subculture.
It’s a lot more than socks. Went looking for a duffel coat once for work and checked both isles in stores. Mens coat - nice woven and well fulled 100 percent wool, thick quality stuff, Women’s isle, cheaper felted wool half the thickness… Same price, same basic style, same store.
Ever since whenever I go looking for stuff I check both isles. Higher quality fabrics are generally reserved for men’s items though women’s stuff is priced the same. You’d never know the difference if you only shopped one gendered option.
