If anyone noticed it or not, Indians faced backlash from all over the world for being loud and basically lack civic sense mainly in tourist attractions and then this one came and sure, everyone knows that India isn't just loud but also saves the world.

P.S. Not really proud of that stupidity by fellow Indians.

Have you ever been to Europe? Have you ever been to the US? If yes, then you would have seen that the immigrants are more an issue than Indians travelling. Because social media shows Indians doing it does not mean Indians do not have a sense of humility and civic sense. Remember, those who are travelling abroad are from the upper middle class or rich class. If they are enjoying themselves, then what is the problem with the left ecosystem?
I have been to those continents as a tourist and their hatred against Indian is immense. It is evident that when China was growing up as a big economy at that time, the Chinese were part of the same hatred.
Racism still exists and I am not denying that and also I am not saying we are doing bad, actually Indians behave well when they move to other countries and the best evidence is following the traffic rules on the road but when the same individual hit the Indian road their muscle memory kick in to keep one hand at horn all the time.

But there are some incidents which goes out of hand, like being very disturbing to the fellow people around the same place.
US people had that similar kind of hatred in 19070s and then Australians and even Chinese too but they managed to change the propaganda over the period.
