A famous streamer visited Argentina and his warm welcome is being used to refute criticism of a social issue. Thoughts? Do you think its valid?

Famous American streamer Speed visited Argentina recently and now many Argentinians on twitter are saying this shows the people who call Argentina a racist country are wrong because he received a big warm welcome.

Genuinely curious what this subreddit thinks because I feel like this topic has a lot of nuance. Does this argument have merit?
