"I think the big difference between the Tyrells and the Lannisters is that the Tyrells are a matriarch family. The Tyrells are run by a woman. Olenna is completely in charge of that family. The Lannisters are run by Tywin Lannister. It’s a very virile, very masculine-dominated Alpha Male family. And Cersei, as Lena has so beautifully portrayed in previous seasons, she feels a bit trapped and dominated and wishes she could have been a man so that she could get on the battlefield and fight. She feels suppressed by her gender. The interesting thing about Margaery is that she’s more cut from the cloth as a protegée of her grandmother, so she knows what it’s like for a woman to be in charge. I’m sure that in Margaery’s head, she’s hoping and believing that she can marry Joffrey, have a son and put her son on the throne and be a matriarch herself."
