People both inside and outside the house are saying that, by bringing Archana back to Bigg Boss, the makers have given a pass to violence.
This is not true! Archana was brought back, but not by giving the reason that violence is not a big deal. It still is, even if its not enough to throw you out of the house (at least this is what the makers are saying). Since Shiv planned to provoke Archana, and brought outside stuff to do the provocation, instead of sticking to matters of the house, he can't be called a victim. Because a victim would never plan his/her own assault for an ulterior motive and bringing outside stuff in the show is against the rules. Now whether this reasoning makes sense or not is not the point. The point is Archana and Shiv's fight was very different from Shalin and Stan's fight.
Stan started it by throwing abuses, and he was the first one to bring outside stuff by going on Shalin's family with the comment "tere baap ka hain kya". Stan came to hit Shalin and Shalin acted in self defense. Shiv shoved Shalin's face while trying to separate Shalin from Stan.
Here, Shalin was the victim because he didn't plan any of this. Saying comments like "tere baap ki aukaat hain, maa ki aukat hain..." can come under provocation but Stan again was the one to first go on Shalin's family.
Stan would get his punishment by getting nominated for 4 weeks. But its unfair to him that Archana didn't get any punishment. Yes, she was evicted, but she came back just after one day, so she was let off the hook easily. Coming to Shiv, he shoved Shalin's face but he did it in a heated moment. But then Shalin also got physical with Archana in a task, when things were heated.
Still he was punished by Bigg Boss, by being nominated and not allowed to be captain for weeks. So Shiv too deserves some punishment. That punishment doesn't have to be eviction, because again they brought Archana back. But even if the makers had decided to evict Stan and Shiv, they would have a point that in this fight there was a victim. Unlike Archana and Shiv's fight, where there wasn't. At the very least, Shiv needs to reprimanded by the host and/or Bigg Boss.
