Ok, at this rate, is there a single country we're not cursing at as netizens? Are we left with only Russia and Japan as the friendly ones? Scratch the surface, and the Japanese also have a certain disgust for India due to the shoddy nature of our cities and overall dirt and pollution.
Everyone and their dog is going to constantly look down upon Indians until we reach 10,000 per capita nominal, and have clean and good looking cities.
We really don't understand just how important cities and public space's cleanliness are in terms of perception. The quality of your cities, architecture, neighborhoods, houses, parks and walkways are the number one quality that the world looks at when judging your culture and race. More than any "ancient history" or GDP figures. That's why California is now seen as a shithole despite having the largest GDP in America. This is an aspect India has been ignoring at its own cultural peril for decades. Even the Swachch Bharat Abhiyan ended as a meme.
Better for Indian netizens to be positive online as much as possible and try to be brand ambassadors for Indian investment opportunities, infrastructure growth, architecture, music and arts. Showcase better parts of India such as the nature in the coastline, western ghats, Himalayas, North East etc, or good parts of tier 2 cities. Not talking about your quote in particular since it's happening in an Indian forum, but just an overall generalization.
