Twitter zoos are voluntarily separating zoophilia not only from other paraphilias, but from sexualities in general.
Nobody says "attraction to men is a sexuality because I want to talk about men and not about living as a queer".
Every other type of attraction, except for peer attracted heterosexuality, has a social component to it, and spaces centered around it are preoccupied with making people's lives better and safer.
Do Twitter zoos just want to be like heteros, at this point? Acceptance for zoophilia while oppression for all other non normative attractions ?
