You can't deny that the Indians started that hostility and went further with that hostility. They've been much worse than others on this front for much longer. Is it any wonder that Chinese hostility towards Indians are increasing now that more Chinese people are made more aware of Indian hatred for Chinese that existed far before Chinese were even mildly aware that Indians exist.
I challenge anyone to spend a few hours reading Indian defence forums. Go back to 2000s if you can even and the Indians' hatred for Chinese is almost as strong as Nazi hatred for Jews.
I challenge you to find racist SDF/Chinese behaviour towards Indians here that is as ubiquitous and intense as Indian racism.
Basically Indians have been calling Chinese "ch*nki monkey" etc etc for over 10 years now while most Chinese didn't think about India or Indians once in a year.
Only since Doklam has Chinese started noticing India and after 2020, more Chinese are finally waking up to Indian hostility.
Again check out DFI from 2010 and check out SDF from 2010 and look at the difference.
Despite all this, we don't call Indians any racist names.
Let me say this, any hostility and hate coming for India and Indians is well and truly justified just as karma for the abuse and hatred they've hurled. When Pakistan lost an airliner to an accident, Indians cheered and made jokes. When China suffered floods, Indians relished and prayed for dams to collapse for more lives could be lost. There are dozens of these types of examples that are committed by Indians. The equivalent against Indians is nowhere near as severe and intolerable or as great in frequency despite India being a greater laughing stock and loser country... sorry but this is simply objective fact, not racism. There is so much more criticism and mocking that can be leveled at India, yet few bother. Indians engage in this all the time to make themselves feel a little better.
