At least personally for me, I don't think it is over the top for television. Also if it violates Indian law or offends sensibilities, the producers can definitely censor what they broadcast on TV. I don't think the two girls can be blamed if the producers take advantage of it.
If it was a one or two hour deal, I would expect people to be more respectful and restrained. But when you live in a house 24/7, I would not expect people to be restrained in their interactions.
One valid objection, I do understand is that it seems one sided (and forced) from Aashka. However, even though Sana does not initiate it, I personally have not seen indication that she really dislikes it or loathes it. It honestly does seem totally Brittany and Santana to me - the blonde and the bitch.
