Regarding samay raina show , just becuase there happens to be a particular set of audience for such vulgarity it doesn't deem the show to be right. It's not even age limit , I feel no one should see such shows irrespective of age. I am not able to understand the mindset of the people who enjoy such vulgarity like that showcased by samar Raina and beers biceps in that episode.
Likewise there happens to be a particular set of people who commit crime, bullying, that doesn’t mean it should be legitimised. Latent jaisa wahiyat show toh band hona hi chahiye tha.
Lastly humour and comedy require wit , intelligence which is not everyone's cup of tea. Dialogue delivery , voice modulation, cracking good jokes require intelligence. Puking vulgarity and hurling abuses doesn't classify as humour.
