Why the anti-government speech was a threat?

Anti-government speech can be perceived as a threat because it may incite unrest, undermine public trust in institutions, and encourage individuals to engage in unlawful or violent actions against the government. Such speech can destabilize societal order by fostering division and hostility among citizens. Additionally, in extreme cases, it may inspire extremist groups or movements that challenge the legitimacy of the state, potentially leading to conflict or civil disorder.
