Why is inclusion necessary ?
Growing up is the action of becoming.
We humans, as many other species, are wired to become what we are shown.
Growing up in a certain culture or a certain family will have an heavy weight on who we will ultimately become. At around teenage we start to search for our "personal" identity and it is a search that can for some, last for a lifetime. What makes it easier is to be shown various possibilities and models to which we can relate, It eases the process. When we can identify, we can more easily see outside what we feel inside and find ways to embrace it.
In a world where the vast majority of imagery only represent a white minority, children of color struggle to identify with the characters and appreciate their own beauty.
