The problem is Arabs have very little representation in Hollywood. So when one of our own stories gets the big Hollywood treatment, it is shitty as hell for the roles to be given to non Arab brown people. South Asians already have a much larger representation than we do. From brown actors in Hollywood movies, to comedians, and to the small screen. We're either cast as villains, or have our roles given to latinos or Indians.
We want representation. The nerves for some people to think, "well just put any brown person into the role, they'll be happy right?!" We don't have many people like us playing these roles.
