Because they can't answer back

Helen is consistently rude about others but turns into a nasty woman or cry baby when it is reversed.

I really think she is the nastiest housemates apart from Pauline.

Im following this but your logic is flawed. Helen spits venom when she has things to say. Her tears were tears of frustration and guilt, not nastiness. I think you are twisting her tears into something that suits your aims.

Well Helen can't answer you back either.

..hmm, that's done with a lot of celebrities..Miley Cyrus seems to be another and then there is Tulisa with how she looks now and any surgery or enhancement she's had done, because she's not liked then it's ok..?../she's not 'human'..?,,and I don't agree with that either/the remarks...for me the biggest one on BB this year anyway was Biannca in terms of criticism she got on forums and social sites etc because she used certain terminology, showed her body and was very 'in you face' but not in an aggressive way, she had dreadful names cast at her of slut/slag/*****/disgusting/vile etc and in the short time she was there, probably as much as Helen has...and I don't agree with that at all but it has to be said that people who referred to Biannca with such names are objecting to Helen being referred to as the same when two wrongs etc..they're both not good to do....and it's the same for Helen when she insults and name calls people in the house, it's not an admirable trait, it's wrong..in no social environment is it right to do that and cross that boundary...and that's why many don't admire Helen...and also why they don't see the bitching by Ashleigh in the same vein because that doesn't cross any boundaries in the same way...

It isn't ok no they are two other examples I guess.
I agree the slut shaming of biancca was brutal I can't think who supported helen and disliked biancca but they might have done even though they got the same labels only biancca behaved erm... provocatively in the house.
At the moment she is poitive as I'm sure helen was initially but i'm really hoping that the negative press and attention BB brings doesn't have an impact on bianccas er... vivaciousness.
Helen has insulted and name called yes, it's not an admirable trait no but it is what it is all bluster and a knee jerk reaction. I don't get the 'in no social environment is that acceptable'... you can't toss 17 volatile personalities, total strangers in a house with no outside contact for months and expect there to be no fallout..
Ashleighs bitching may not be seen as in the same league not sure why though... it's the same only not as loud.
What 'social boundries' are there to cross apart from some snobbish misconception that it's ok to whisper bitch and collude in corners but not express your inner frustration audibly?
