1) BB has never had a diversity issue on the show. African Americans make up around 13.5% of the population so we should expect around two or three each season. POC aren't losing because of racism, it's a numbers game and whites have a six times better chance of winning the competition. Saying that it's race related is actually being racist.
2) Every time someone is voted out we get a good idea as to why. Never in the history of BB has anyone been voted off because of their skin color. Nor are they the first ones being voted off each season like I'm reading in some of these post. It's an absolute lie that can easily be checked on-line.
For those of you biased against white people (or vice-versa), I can promise you your life won't be as joyful as it could be. There are good and bad people in every segment of society; no race has moral authority. Speaking of which, if the roles were reversed way back when, would there be any specific reason blacks wouldn't have made some white people slaves? Do they have a moral advantage in their make-up? No. So why hold people to standards that you wouldn't live up to yourself?
Try not to judge people and have negative thoughts towards people you don't even know. Honor the memory of the great Dr. Martin Luther King, Jr., and judge people on the content of their character. Thanks.
BTW: Big Brother knows they messed up by not addressing this double-standard in how races are treated on the show. If a group of white people got together to create their own team so they could vote off blacks, the media world would come unhinged. This isn't good for race relations when one group can get away with things other groups can't.
