just because you can’t understand how something works, doesn’t mean it doesn’t exist.
i don’t understand how matter collides in space to make stars, yet there they are every night.
i don’t understand why my brain has chemical imbalances, but here I am with my mental illness.
and the same can be true of gender. just because you can’t understand nonbinary genders (and yes even those that you consider ‘cringey’) doesn’t mean those people don’t exist.
there is no reason on Earth to insult and belittle another human being just because you can’t understand how they feel.
and quite frankly if you can’t accept that, just ignore it and move on. no one is forcing you to harass innocent people.
