They all talk about themselves so I don't know what the problem is either. Also I think some people have already formed their opinion based on how Sophie was in other reality shows, however I haven't seen any so can only base my opinion on what I've seen of her in the house.
I suspect that Sophie is an easy target in there as, once a group have a dislike for someone it's easier for others to follow suit.
Sophie has her faults, as do we all, but I don't think she's done anything nasty.
