I don't know about 'naturally bitchy' but women and girls are being encouraged by gossip magazines and bitchy women characters in soaps like Eastenders.
I read that is one of the reasons for more bullying in schools.
Had to laugh when I read Polly Hudson was complaining about the bitching and bullying by Jade, Jo and Danielle in CBB when she used to write for Heat.
Also another thing was Danielle saying in her eviction interview the way she acted was 'just girls being girls'. She doesn't even know she was doing wrong.
