Well not you apparently.
I honestly don’t care. I’m white. If there are all white characters, I probably wouldn’t even notice.
But, I have empathy for other people, so I understand why one would care if they never see themselves represented in the popular culture, like these large tv productions.
And, since I’m not a bigot, I don’t mind if people of colour are represented in tv shows that I watch. If it’s a good show, with good acting and writing, then why would I care?
