I never said anything that implied all black characters are alike or all white characters are alike. I made a simple point...the diversity that really matters when it comes to creating a good show is personality diversity. Racial diversity does virtually nothing to improve a show. We've had many classic, brilliantly written shows with little to no racial diversity. The Dick Van Dyke Show. Cheers. Seinfeld. The desire to make shows racially diverse has almost everything to do with a social agenda and/or marketing but very little to do with increasing a show's writing quality. Of course you can have personality diversity and racial diversity at the same time. But when it comes to casting, the question should be which actor is best for the part? Not which actor will fill a racial quota. Which actor on Cheers or Seinfeld should've lost their job because they were the wrong race? Woody, you're great but we want a black man for this part. Kelsey, you're perfect but we were looking for a Latino. John R., great job but we're trying to find an Indian to play Cliff. If you've found the perfect cast, nothing should impose upon you to change it based on the actors' races. Every actor of any race should be allowed to try out for the parts, if the character has no story-based reason for being a certain race, but the best actor for the job should be the one who wins the part. There's certainly a difference when you're casting a show based on a pre-existing character or real-life person. In that case, the top criteria should be casting someone who looks like that pre-existing person. That's why a show like SNL benefits from having a racially diverse cast. They need actors who will match the physical appearance of various pre-existing people they will need to play. If someone finds script opportunities based on a character's race, it almost always means they're buying into and promoting racial stereotypes. How many stories or character traits can be written for a black character that can't be written for a white, Asian, Indian or Latino character? Unless you're specifically doing a story about racial prejudice or the character is an immigrant from a non-racially-diverse country, there are very few non-stereotypical reasons why a character would need to be a certain race. Yes, there's an economic difference between blacks and whites in the U.S., so if you have a poor character it's more realistic if they're black, but it's not necessary. Could Gilligan's Island be rebooted with an all-black cast? Sure. But the only reason to do so would be if someone thought there would be a marketing benefit to it. It wouldn't improve the stories or writing. Most people would expect a reboot of it would have some racial diversity. But as I said above, I would argue the best version of the show would be one that hires the best actors for the job who have the best chemistry together. Race shouldn't be anything that scores any points for the actors trying out for the parts one way or the other. So far there's not much to back up that racial diversity has any effect on increasing the popularity of entertainment. Some of the most popular shows in reruns continue to be non-racially-diverse shows like Friends and Seinfeld. The Office is booming in popularity now and, I've never seen it, but the DVD box covers seem to be full of white people. Big Bang Theory, I've never seen, but it also appears to be light on racial diversity. The most popular shows with black characters tend to be shows with almost ALL black characters like The Jeffersons, The Cosby Show, Family Matters, Fresh Prince, etc. Most of these shows tend to be trying to reflect a reality that people can identify with. And the reality probably is that people's families and groups of friends tend not to be racially diverse. There probably isn't even much racial diversity in schools and workplaces in most of the country. Schools are probably the place where people most encounter racial diversity and TV shows about schools have tended to reflect that in the casting. Most school shows haven't been that popular, but Facts of Life had a long run with a black actress among the four leads. And that's probably because people can relate to going to school with people of different races. One exception is definitely Diff'rent Strokes. It had a cast split racially in a family that didn't reflect the reality of most of its viewers at all. In that case the very comic premise of the show was to see what would happen if an upper class white family adopted two lower class black boys. So there are cases where people want to see comedy that's not realistic or reflective of their own lives. Gender diversity is a different story. Almost all people live and work in gender-diverse groups. So shows with all-male or all-female casts tend not to be the most popular shows. Definitely exceptions, as Odd Couple and Perfect Strangers show a two-man buddy show can be popular. And female ensemble shows like Golden Girls and Facts of Life have also found their audience. Still, these shows never reach the top echelon in ratings. Casts with mixed genders in the leads tend to be the most popular.
