Hong Kong activists have every right to protest against the impending national security law. But they have no right to recruit and mobilise schoolchildren to join them. One of the tragedies of the widespread unrest of last year has been the radical politicisation of secondary school campuses. Not only are they collecting signatures on campuses, but they are also actively preparing them to boycott classes when schools have only just reopened after a period of closure due to the Covid-19 outbreak . This is a continuation of last year’s cynical exploitation of young children to fight the government during violent protests, leading to a high number of arrests among the underaged in confrontations with police. At least 23 labour unions, spanning 20 industries, including aviation, transport, construction and information technology, have answered the call of the Hong Kong Confederation of Trade Unions to prepare for strikes after a so-called referendum . There is now a group that calls itself the Hong Kong Secondary School Students Action Platform, which is supported by Demosisto, the radical political group headed by well-known activist Joshua Wong Chi-fung. Will new security law ruin Hong Kong opposition’s plans for Legco polls? The protest groups will first conduct a referendum to seek public support for citywide strikes. But given their low threshold and target audience, the result is a foregone conclusion. The Hong Kong Professional Teachers’ Union, an opposition outfit, is expected to join the strikes. So far, it has said nothing about involving children who are supposedly under the care of many of its members. Young people are passionate and idealistic. That’s why university students are often among the most radical and committed of activists. Nothing wrong with that. They are young adults beginning to gain independence and learn critical thinking. China itself has had a long history of student radicalism, from the May Fourth Movement to the student-led occupation of Tiananmen Square in 1989 . But secondary school students are not adults, nor do they have enough maturity to stand on their own. Parental and teachers’ guidance is not only justified, but necessary. You have to question why they are being involved in expected protests and strikes whose purpose we all know will fail. The security law is dictated by Beijing , and there is nothing the Hong Kong government can do about it. The only conclusion is that the opposition just cynically wants to radicalise and brainwash a new generation of children.
