I wouldn't blame neither Aaryn, Gina Marie or Jeremy of anything that could happen in this show, I think they are not guilty of anything except their own stupidity of saying those things on TV, I wouldn't even mind to see Aaryn winning this thing, if they want to be shown as racists and homophobics, that's their thing, we have seen what happened with the two girls, they have been fired from their jobs. I blame Alison Grodner if Big Brother US is hurt, she could stop this easily, not with their ejection, but with a formal warning when the first racist/homophobic comment was made, if BB is hurt.
Who has the fault of the bad reception they are having outside? The housemates, that are the ones who are talking, of course, they are guilty of their actions
Who has the fault of the bad reception of the show? Grodner, who seems very busy searching BB 14's Frank photos in the shower in Google Images but not with what happens in that house
