I just love how we have children's stories like «Ugly duckling«, «Lion King«, «Jungle Book« and «Tangled« where the main character is separated from their own kind or own family and that separation is seen as a negative thing. If the separation has been done on purpose and so the person separating the protagonist from their parents can benefit from the protagonist, the person forcing the protagonist from their own kind is a villain in the story. The process of the protagonist finding their roots is usually very crucial for the plot of the story in a positive way.
The ugly duckling grows to be a beautiful swan, Simba becomes the real king of his kingdom, Rapunzel finally gets to see the real world and her biological parents.
My point is even in children's medias separation from own kind and own parents are seen as a bad thing. But as adoptees we are assumed and maybe even pressured to be grateful for the thing everyone sees as misfortune. People see adoption as a bad, unfortunate thing and everyone is happy it didn't happen to them but adoptees should be grateful for their adoptive parents for adopting them.
I know my life would be so much more difficult if I grew up as an orphan in South-Africa especially when there's been serious problems with femicide and gender based violence for past seven years. At the same time I don't know how I would be able to be grateful for being robbed my culture, my experience of being South-African. I should be grateful for being robbed my biological family and the experiences that come with growing up with people who look like me.
