Faggots will sexualize and get horny for any design, of course it's easier for them to sexualize something humanoid, but if they couldn't find anything better, they would fap to something like electrode or swalot. Also consider that their minds are trained to sexualize anything that resembles a female or a mammal, so it's natural that they will immediately think of pokemon like Zoroark or Delphox as being designed for the purpose of being 'sexy'.
Have in mind that faggots = gay, furry, fetishist, tranny, etc. All of these overlap eachother and are a result of males not being able to find a female partner due to the extreme SMV of women compared to men. So as a coping mechanism they develop fetishes and sexual deviations.
