On 5 December 2020, Millwall played against Derby County in the first game back at the Den for fans in ten months due to the COVID-19 Pandemic. Some of the 2,000 fans present booed the players who took a knee and raised a fist before the game in support of the Black Lives Matter social and political movement. The booing was condemned by The FA, EFL, Kick it Out, and mainstream media. Cabinet minister George Eustice refused to condemn Millwall fans, stating Black Live Matter political movement was against what most British people believed in and fans should be free to express their views. The leader of the Brexit Party Nigel Farage called BLM a Marxist Party who had been "sussed out" by Millwall fans and called for kneeling to stop. In the next game at the Den against QPR on the 8th of December 2020, Millwall fans applauded as QPR and Millwall players raised aloft an anti-racism banner about inequality in football. The 2,000 Millwall fans also cheered the QPR players who took the knee. No Millwall player kneeled. Before the game, every fan was given a letter from the club saying, "The eyes of the world are on this football club tonight - your club - and they want us to fail. Together as one, we will not let that happen." Some Millwall supporters had said their boos at the Derby game did not have racist intent, but was instead against the politicisation of the Black Lives Matter movement in the UK.
