Years before pictures filled our screens of protesters kneeling to demand an end to systemic racism and police brutality, Colin Kaepernick cast a desolate figure on the American Football field. Kaepernick was the star quarterback of the NFL's San Francisco 49ers. Back in the 2016 season, he would 'take a knee' during the American national anthem to protest racial inequality. The backlash was tremendous and, whilst he was not the only high-profile athlete trying to draw attention to social issues, Kaepernick has been unable to secure a place in an NFL team since.

Roll on to 2020, and whilst Kaepernick's actions are starting to be widely vindicated and copied, another high-profile athlete - English football star Marcus Rashford - has this week almost single-handedly been responsible for the British Government's u-turn on the scrapping of the school meal voucher programme. With it, 1.3m school children in Britain will not go without at least one proper meal during the summer holidays.

Star athletes are easy to criticize. The fame, the fortune, the lavish lifestyles, the luxury, the excesses, are big targets. We expect our sporting idols to be infallible role models, forever grateful and humble for the unique opportunities afforded to them. We come down hard on them when they burst our bubble - when they fail to score the goal, when they miss the pass, when they lose the final, and, gasp, when they dare pronounce themselves on social issues that have affected them and that continue to affect many like them in their communities. Even basketball great Lebron James was told to "shut up and dribble" when he spoke up against President Trump.

Despite this maligning, sport and social justice have a long and positive association. From the NBA's Bill Russell fighting racial segregation, Billy Jean King winning tennis' "Battle of the Sexes", Tommie Smith's black-gloved fist salute at the 1968 Olympics, Magic Johnson's stand against HIV, Jason Collins becoming the first openly gay NBA basketball player, the US Women's Soccer National Team's fight for equal pay, Serena Williams and Michael Phelps speaking about their mental health issues, and Lewis Pugh drawing attention to melting sea ice, star athletes have always understood the strength and reach of their platform.

For this reason, the praise and admiration for the likes of Kaepernick and Rashford is as refreshing as it is deserved. Athletes have a wide following, and their actions are pervasively influential throughout society. Highlighting social inequality and fighting against it sends a powerful message and with a reach that few other spokespeople can achieve.
