A reminder to fandoms:
Things that are okay: Having a headcanon about a character’s age/sexuality/gender/ethnicity.
Things that are not okay: Imposing your headcanon on others and harassing them if they don’t agree.
Things that are even less okay: Accusing someone of serious things such as homophobia/pedophilia/transphobia for something as stupid as not sharing the same headcanon as you.
