Minorities are becoming the majority. I understand catering to women and different races. We all like to relate to the characters as much as we can. That's part of our reasoning for liking certain characters. But when you try to replace such longstanding characters with new characters, and of different race, longtime fans of those characters are immediately no longer interested in these books because those are the characters we buy these books to read about. But when our favorite characters return, we will read again.
