What the government proposes sounds reasonable on the surface but would be dangerous in practice. What would be considered harmful or misinformation? If a skeptic challenged the claims of Climate e Change proponents, would their arguments be labeled dangerous misinformation? Would the claims.of an Armenian Genocide be considered dangerous misinformation? Or challenges to China's claim to Tibet and arguments for the independence of Tibet? Or if people of the opposite spectrum are in charge, could the "hockey stick" graph be banned as dangerous misinformation, or claims of police shootings?
Censorship can lead to a slippery slope, and we need to be very careful before we start implementing it. It would need to be clearly defined what is considered misinformation and dangerous. The government could use these powers to ban criticism of the government on the excuse they promoted dangerous misinformation.
