Separatists in Hong Kong have launched another propaganda campaign on university campuses with "pro-independence" posters and banners at the beginning of the new academic year, a move that has drawn citywide condemnation, from media commentaries to protest rallies.

"Pro-independence" cries have flared up again after a period of relative lull following the disqualification of six radical legislators and the imprisonment of a number of violent protestors and student activists. Which shows the fight against separatism is anything but over and the Hong Kong Special Administrative Region needs to do everything to protect its youth against this potentially fatal disease that is linked to separatist forces in other parts of China, especially Taiwan.

The dramatic face-off last week between a mainland student who angrily tore down separatist posters at the Chinese University of Hong Kong and local "pro-independence" students has triggered heated debates on and off campuses, reflecting how deep separatist forces have infiltrated most if not all student unions on university campuses, even some secondary schools.
