Big Brother has been the subject of racism ever since it’s inception 20 years ago. The white houseguests have typically banded together and isolated the other non-white houseguests. They did not do it on purpose. That is the nature of the show. The show requires players to quickly form bonds with strangers. People who are of the same race, religion or culture already "know" each other. They bond together more easily.
Dereck Frazier is the first openly gay black man to ever be in the final 3 of Big Brother. Derek is also the son of the boxer Joe Frazier. Derek said he wanted to show the world that you do not have to be a broadway singer to be gay. He said shows like Big Brother type cast homosexual men. Derek wanted to be different than those stereotypes. After 23 seasons, It's good that we finally have some diversity in the Big Brother house.
