Furries do tend to be more open about kink (as part of the community’s general culture of acceptance), but to describe furry as a “kink subculture” is misleadingly reductive at best.
It's not a kink subculture. There are kink subcultures within it, but the only common factor among all the subcultures inside it is an appreciation for anthropomorphism.
(Do other kink subcultures do this stuff??)
