LOL no, it isn't. If you're trying to compare whites in professional sports to blacks in Hollywood, there isn't a comparison. The team owners are majority white, the executives are majority white, the coaches are majority white. The gatekeepers of pro-sports are predominately white, yet the players are predominately black.
How on God's green earth does that negate the comparison?
Both are entirely profit-driven institutions, and TALENT ultimately fills the coffers. Everyone knows blacks clearly dominate on the court. Franchises tend to be more competitive and profitable when they're stocked with 6'8" brothers who can hurdle a Range Rover and sink outside jumpers with reliable consistency. And far as I know, no one has ever suggested (or even thought about) boycotting the NBA for its lack of diversity.
Hollywood's exactly the same: white, black, brown, yellow = meaningless. "This town only recognizes one color," Morgan Freeman once said: "green." If you have the talent, star appeal, or whatever intangible big screen quality that puts asses in seats, studios will be bombarding your agent with scripts.
What difference do the owners' and execs' races make? They pay these folks millions for their talent, knowing damn well the investments will eventually pay off in, ahem, spades. Isn't this precisely how a market-driven economy is supposed to work?
