I know the answer is they're fucking racists, but for the sake of ranting I'll pretend to look for a better reason.
They claim it should be an American. He fucking IS American. Puerto Ricans are as American as Nebraskans. Puerto Rico is part of the Untied States. Also, have these fuckers even watched the super bowl before? It's been done by non-americans lots of times!
They claim it should be someone who speaks English and appeals to an American audience. Spanish America is part of America. Even as a Canadian, I know that the Spanish language and Latino culture is interwoven with Untied States culture because I grew up watching American shows that teach Spanish. Barney. Dora the Explorer. Maya and Miguel. I can't imagine being so damn hateful as to not want a large percentage of my country to feel included. To claim I'm being excluded because things are in a different language than English sometimes. Oh no, I'm so oppressed by having to press 1 for service in English. You all probably had no issue dancing to the macarena without knowing what it's about, why is it a problem to listen to Spanish language music now?
They claim it shouldn't be him because they never heard of him. I never heard of him before this either, but I realize the world doesn't revolve around me! Just because you personally never heard of him doesn't change that he is an accomplished musician who is very popular and won many awards.
They claim Bad Bunny hates America because he made the smart decision not to tour in the mainland Untied States for fear of ICE raids at his concerts. How dare he recognize that the regime is a danger to his fans. How dare he recognize the horrors the regime is committing.
Of course I know looking for a remotely good faith reason is an exercise in futility. The truth is the Untied States has a lot of racist fucks who just got permission to be out and proud racist fucks
I get that these people think their culture should be the only one in America, but to me it is ridiculous to exclude Latin culture from American culture. American culture is an amalgamation of many cultures, including Latin-American culture, African-American culture, Navajo culture, and many many more. Just like Canadian culture is an amalgamation of Irish-Canadian culture, French Canadian culture, Inuit culture, and many many more. It's so ridiculous and disgusting that the people currently in power in the Untied States are trying to extinguish most of America's cultures and they think that makes them more American
