Depends on your definition of abundant.It being a "white industry" isn't the point I'm addressing, in fact I grant you that it is (would be ridiculous to deny that). However in this day and age, Good, black actors are abundant in both film and television.
I just gave you a list of dozens of movies, with only one or two of them being lead by non white actors. You throwing out a couple names doesn't refute that. It's you doing the "chery picking"
Like I said it's a well documented issue. I don't know why you chose to deny it.
