So, you’re a writer and you’re worried about writing outside your immediate experiences and identities.
Here is the thread of practical advice for you.
EXAMINE YOUR MOTIVES. Why do you want to write this?
Are you trying to solve racism/sexism/colonialism with your work?
As writers we love stories about heroic writers whose work has changed the world. And as such we like to look to our own writing to solve societal problems.
And I understand this completely, not the least because I’ve felt the pull.
But if you’re looking to play saviour with your words, it is unlikely that you will do the marginalised people you are trying to save justice.
And I understand this very often comes from place of good intentions, but there is a reason that most of the moralising plays written by white abolitionists are deeply uncomfortable to read.
It is incredibly easy for works looking to play saviour to become patronising or traffic in simplistic stereotypes that ultimately hurt the people they are looking to rescue.
