Hardly surprising that study indicated this. Prior to the rise of political correctness in society Christians were the most racist people on the planet and hated non-Christians. Read the views of Winston Churchill on India for example. Here is a quote, “I hate Indians, they are a beastly people with a beastly religion” If you removed the political correctness, they would be back to their old ways. Academic institutionalized racism still goes on against India. There was recently a huge controversy in California by Hindus against academic textbook representations of India and Hinduism which were high racist.
Even I encountered academic racism against Indian philosophy when studying philosophy at uni with my professor. I recently talked to a professor of Indian philosophy(who is white-Western) at Kingston college who relayed to me the massive prejudice he faces in his department against Indian philosophy and who related to and sympathized with my experience.
The way I see it is there is going to be a clash of civilisations in not too distant future. Indian vs West; Abrahamic vs Dharmic. It is the Mahabharata all over again - dark against light. This will happen because modern science itself is becoming dharmic and the remergence of Hindus on the world stage.
