I read Hatimoon's post and I think it has a point.
I feel that there is a difference between Sitara being rude to Saba and Junaid and Salar being rude to Taya. I have not watched the episode where she was rude to them but understanding the context you gave I can get it. Salar knows about Sitara's family and he has an impression about them because he was with them personally, even though Taya was caring towards Sitara before but later he was also the one who agreed to get her married to a middle aged man with children(if I am not wrong). I can understand the Twitter people regarding not calling out Salar for disrespecting Taya.
On the other hand, Sitara knows nothing about Saba and Junaid personally and if she was rude to them because they were defending Salar, it's not done.
That's what I am exactly saying. It is not done. I can understand even why Salar was rude to Taya but it is still not done. As I said, Salar should have been assertive but not insulting. Yes, definitely Sitara's family deserves it. But at the same time, it leaves a very bad impression on Sitara who loves her Taya and her brother and makes her hostile to him. It is one thing that your family is mistreating you but it is another when your partner (or pseudo-partner) is doing so even if it is on your behalf. Also, as of now, we do not know how that interaction between Saba, Junaid and Sitara began and how it reached that point. So I am going to wait for it, but it is still not done. They both need to grow up and seriously so for their marriage to work.
As for twitter, the point is not at all balanced out there. Sitara bashing seems to be the latest sport. Yes, she is being undeniably stupid, mannerless and ungrateful. But Salar is no saint either. He is being whitewashed thanks to his recent grand gestures while his smaller and earlier larger actions which have negative consequences are being ignored.
For this he felt happy when Zuhaib threatened to kill his own self.
