I honestly think Saloni Gaur should stick to mimicking celebs. She does a great job with both Kangana and Sonam. Comedy should be about punching up & not punching down and when you caricature a minority/oppressed community the likelihood of the latter is very high.
Many have already pointed this out so I really hope she considers this, apologises and moves on. She is only 20 so when criticising her please be a little mindful about it.
