This is where I disagree. I was a foster carer to (mainly) teens, some straight, some not, some white, some not, some spoke one language, some spoke others. All came from a long line of foster-hopping (or institutionalised 'care'). The one thing that united them: all labelled incorrigible in some way by someone in the system. They came to me in pieces. No two the same, except they were young and in a difficult situation, abused in too many ways by too many people to trust anyone. This was my life for 30 years, until one of the 'parents' twice attempted to kill me.
Back to the point:
If I write a story about being a foster kid, do I go to the kid who's a different race, or a different face, or a different language? Do I ask the ones who had it bad, or find the rare few who had it good (I met one, once)?
Choosing one person from a group isn't representative, and there is strong bias, even abuse, within a group of people as to 'right' or 'might' when it comes to self- or group-perception.
My cousin (also my best friend from childhood to her recent death) started life with dangly bits. She changed as soon as she turned 16, despite the world turning against her. She went through many kinds of hell, including the abusive male psychiatrist who had to approve her state of mind, had to travel overseas to get the surgery (which was botched), and suffered many forms of abuse (including being put in a male prison for a traffic infringement). Included in that abuse were the people she once considered friends: members of the LGBTQI community, family, employers, teachers, etc. who had all at one time professed to have her back/best interests at heart.
People are fickle, regardless of which community they align themselves with, and any beta or sensitivity reader can only ever share their views as an individual, not as the spokesperson for the whole group. I will trust the view of one person on the day I trust that AI can accurately tell me my life story.
It's fine to do research and to get a wide spectrum view on the subject matter in order to avoid problems, but to trust one small sub-section? Not for me.
A paraphrased quote from Voltaire:
Life is full of thorns; move quickly through or become entangled.
What that means to me is that getting entangled in the expectations/rules of others will lock you behind a thorny wall and put your mind to sleep for a hundred years.
I won't assume that all people within a group/community/label are the same, or share the same views. I won't assume anything. But I will write what I know through research, interviews, life experience, and any available primary sources.
-- I will delete this if people find it offensive. Even one objection. So don't ghost, speak up.
