From the feminist revolutionaries at Medusa Magazine:
Pets cannot speak for themselves. They cannot tell you that they are being misgendered. It’s important not to make assumptions about what gender your animal is based off of its sex.
Hold on, it gets even crazier:
Sex and gender are separate things and are in no way intertwined. The sex of your pet is irrelevant. The only time you need to concern yourself with the sex of your pet is when you spay or neuter it (and this begs the question of whether or not we should perform operations on our pets without their consent). Animals can have diverse genders just like humans, and they can have diverse sexualities also.
Owners are advised to give their pets gender-neutral names and use gender-neutral pronouns. You wouldn’t want to offend your pet, which might be a trans-pet.
Also, it’s an important way to practice getting rid of gender norms all together [sic].
Good Freaking Grief! What type of loon thinks up this stuff??
