Isn't the point that Kendra understood immediately what Edwina was trying on? She knew that Edwina wasn't interested in having the discussion or being objective, she realised Edwina was determined to misconstrue what she was saying, to not let her finish explaining her beliefs and to twist what she meant around and feed it back to the captive audience.
Kendra was affronted and rightly so that someone would be so rude as to interrupt and attempt to override her when she was herself wrangling with how to express a subject that had huge meaning for her, she was opening herself up thinking she was with friends before she was unjustifiably attacked from an outsider to the situation. She reacted defensively in an emotional way because of her youth.
Edwina knew so well what she was doing, looking for the chink in someone's armour to try and tear them down and seizing upon a few words taken out of contest to try to paint someone into a corner. The actions of a lowlife. or a politician.
Edwina Currie, the parasitical politician that she is, sensed vulnerability and made her move, thinking she could get one over on the dumb (in her mind) blonde, American bimbo, she just didn't expect the girl to have so much self belief and inner strenght about her.
She was scalded lol. And is was really obvious when she was sitting by the fire later, she kept looking over and Kendra slyly and she didn't look smug at all, she looked like a pricked balloon.
Kendra did a great job of being fearless in the face of blatent hostility and bullying from Edwina.
Edwina was trying a little of the Delphi principle on her, that is, trying to get the others to turn on her and make her feel isolated into silence with her opinion. She was convinced this old bully tactic would be successful and staggered that it failed.
I love the way Kendra just sees Edwina for the sly, underhanded, manipulative, fraudulent old crow she is and wasn't one bit fazed by her notoriety Edwina thinks all us little people are going to kowtow and is in a state of shock when it doesn't happen. Kendra talked to her as an equal!!!. The people that don't applaud Kendra are afraid I think. Afraid because they know deep down they haven't got the same courage and would probly lick Edwina's boot in the right circumstance.
