Bob's Your Uncle was included in the "yellow YouTube circle" in which netizens backed channels that were in favour of the 2019–20 Hong Kong protests. Uncle Bob said that as a businessman, he supported the yellow economic circle and joined a 12 January 2020 rally in favour of it. He said that owing to the 2019 Yuen Long attack, numerous people in the Hong Kong middle-class "turned yellow", and this is "all because of the government, Black Police, and police violence". He forcefully denounced the Hong Kong Police Force for making numerous arrests he considered indiscriminate including of weak old women.
