It shouldn't mix but they do unfortunately. As much as I would love to say "leave politics out of this", it's kind of ridiculous for a sport such as basketball played at the most highest level in the most popular league in the world to completely dismiss what's going outside in the 'real world', especially since the sport is predominantly the colour of the oppressed. Sports are a getaway for many I get that. In a way, there is a positive side for the mix. I believe the NBA played a role in the election of Joe Biden, especially Stephen Curry who openly endorsed Biden for President. I believe he helped play a part in him capturing California (which has the most electoral seats). The faces of the league are very well-known and they can use their gigantic platform to help make change. In such a popular league, this sways many people to make change.
