Neopronouns are not a “tumblr fad”. Gender neutral pronouns other than they/them have existed in the English language for actual centuries. They are not harmful to the trans community.
To those who are against neopronouns, you’re acting against the evolution of a language and acting against something that’s been around for far longer than you’ve been alive.
To those who use neopronouns, your pronouns are not harmful. You do not deserve to be made to feel ashamed for your pronouns.
