Indians are so easily triggered when any hint of attack that deals or talks about their country's supposed negative side. Here we have, an Indian ethnic-American politician, Nikki Haley making a tweet regarding CO2 in which she essentially tried to put the blame on climate pollution to both India and China. The Indians erupted in an uproar where they attack Nikki Haley's comment and Nikki Haley herself.
Indians are butt hurt when they're attacked or perceived slight when the level of propaganda against them is so tame coming from the west. I can't imagine them handling all the hate and attack if and when India lives up to the lofty promises heaped on that country by many western and Indian pundits as the next China.
