Very good points, and well said.
If I may try to understand and speak for those who've voiced such opinions, I think it's a case of labelling someone as 'bad' - as simple as that. As my 3 year old would say - I don't like her so I don't want to like her. Profound words for a 3 year old, but very true. I think that's what the forum is doing.
When she said 'hum itne kathoor nahin ke ek behn ko doosri behn ki shaadi mein aane se rookein' I actually sympathized with her. I think the forum is just finding flaws in everything she does just because she doesn't like Manvi. And we all LOVE Manvi. So that maybe why the forum is reacting the way it is.
As for her being a single woman and living at her dad's and manning the house - that may be a consolation price. My cousin's divorced, and the oldest daughter in the family and lives with her parents. So whenever we visit her, and her brothers and SILs do, we listen to her coz she's the oldest. It's out of respect, and also the fact that since she's the daughter of the house, she's been there longer and would of course understand and relate to the parents, every day on-goings of that house the best. So we defer to her on day to day matters, and value her opinion in the bigger matters too.
That said, she knows her place. Swamini, I feel, is suffocatingly rigid, as you pointed out, but there may be a story behind it I feel. I think the dadaji is worse. Swamini atleast seems to have a heart. Yes, she hates Manvi and her thoughts are downright petty. But she does have a heart. What dadaji does with his one minute rule, and the way he treats Virat and Inder, his own blood - I feel is just out of this world. So all this maybe related to Swamini's behavior.
We're all products of our upbringing and surroundings. Each and everyone of us. So is Swamini. She does things in that house because that's how she's always done it, that's how it's expected of her, and that's how it's been set.
Oddly enough - after today's episode I felt like everyone in that family is just sleeping in this sweet dreamy sleep where they do NOT want to be woken up from. Things are unfair in that house and no one WANTS to know it, they would rather go on sleeping, and believing they live in this beautiful house, with a beautiful family, with a very respectable dadaji at the helm and a very kind disciplinarian as Swamini. No one will 'wake up'. The only one awake enough to see what's wrong is Virat, but he's accepted that it'll be this way and has moved on.
I think that's precisely what is going to change in this house - the slumber it's in. And it'll be Manvi causing the rousing. It'll be interesting to see.
But circling back to your topic - we've advanced (psychologically) enough to know that women aren't 'burdens' shoud they live with their parents. They have voices and opinons as much as the other person, and just because they're voices and opinions don't jive with ours doesn't mean they don't have a right to them. If anything, Swamini has more rights to such opinions coz it's HER house. HER father. When I go to my mayka, I can ALWAYS tell my parents what I think maybe wrong or right, w/o hesitancy. But yes, when it comes to matters with my brother and SIL, I maintain a certain respect and distance because they are their own family unit now so my opinion is given while keeping my respect for my bro and SIL in mind. That said, every girl will ALWAYS be more at home in her mayka than in her sasural (yes there are some exceptions), and she will and should always have the right to speak her mind.
Swamini's being head of the family may simply be that way coz she's the oldest.
