What is the point of equating following and supporting an athlete or a country in a sport with the possibility that an entire people is racist?
By that logic we shouldn't read and support any manga given the accusations that many Japanese people are racist.
Actually that video script is made by using chatgpt with little research and doesn't present a nunanced and balanced perspective on the history.
How I know this isn't important but I am 100% certain that the creator made the video with little research and using AI platforms.
Second, there's nothing wrong with supporting a country because you like an individual. By that logic, many people across the World shouldn't support France due to them being Mbappe or Real Madrid Fans.
Third, Supporting Argentina in football because of Messi does not mean someone is endorsing every attitude or historical wrong associated with Argentine society or history.
By this logic, we shouldn't be supporting any country with colonial history. And, we know how racists, unfair, oppressive and unjust these European countries were to their colonies.
Also, it is fair to criticize racism, offensive language, or Argentina’s history of racial erasure, but it is not fair to assume that all Argentines think alike (this is generalization) or that all foreign fans are blindly defending racism simply because they admire Messi or the football team.
