Public figures in sport haven't always been expected to share their political views, but as the world evolves and social media brings fans and athletes closer than ever before, it's become increasingly common. Although the
International Olympic Committee continues to insist that sports aren't political, others (including Nelson Mandela) have always recognized the inherently political nature of events that bring people from all over the world together.
Some star athletes, like Muhammad Ali and Billie Jean King, were speaking their minds and fighting for change long before the age of social media. These days, it's easy for sports personalities to speak directly to their fans and share their thoughts and feelings on issues of social justice and governance. However, doing so always comes with a risk to their careers.
