Acknowledging the limitations on such a metric, if I were to be asked for my intuition on the rankings of least racist countries, I think it would come pretty close to the rankings of your study. That said, even if we accept this one very limited study, and my own very limited intuition, as truth, what does this tell us? That we need to stop fighting for racial equality, because we are more open to people of other races than India? Imagine a reverse kind of thread, where a liberal brings one ranking of least socialist countries with the US at the top (a list that would not be hard to find). Would you come to the thread and instantly agree that “the con socialist talk is tired.”?
