The Debate Over Freedom of Expression Rekindles on Online Platforms With the rapid growth of digital platforms in the 2020s, the online environment for sharing personal thoughts and opinions has offered unprecedented freedom. However, this freedom does not always manifest positively. As discriminatory and violent language, often disguised as hate speech, has permeated digital spaces, the boundary between freedom of expression and the regulation of hate speech has once again become the focal point of heated debate. The New York Times recently emphasized in an opinion column that freedom of expression is not an absolute right. The publication noted the severe harm and social division caused by online hate speech to minority groups, maintaining that speech infringing upon the rights of others or inciting violence can be legitimately restricted. It specifically argued that online hate speech poses a significant risk of leading to social problems due to the direct and tangible harm it inflicts on minority groups. The New York Times called for platform companies and governments to intervene with a stronger sense of responsibility. It is no longer a mere apprehension that digital violence and psychological attacks can lead to real-world social divisions. Indeed, a 2024 European Union (EU) survey reported that 67% of minority group members exposed to online hate speech experienced depression or anxiety disorders. In contrast, The Wall Street Journal presented a different perspective on the same issue in an editorial. They warned that freedom of expression is the cornerstone of democracy, and that hate speech regulation could potentially lead to excessive censorship by governments and platforms. The Wall Street Journal pointed out that the definition of hate speech can be ambiguous and subjective, expressing concern that such regulations risk devolving into excessive censorship depending on political and social circumstances. They also emphasized that it could stifle free debate and the exchange of ideas. Their stance is clear: even hate speech should be protected within the broader framework of freedom of expression, and the solution lies in fostering a healthy public discourse through counter-argument and education rather than regulation. In the United States, freedom of expression is strongly protected by the First Amendment, and according to 2023 statistics, 78% of American adults responded that "offensive speech should also be protected as freedom of expression." This leads us to an important question: where exactly is the appropriate balance between freedom of expression and regulation? In Korean society, this issue has already become a reality. According to 2025 data from the Korea Communications Commission, online hate speech posts increased by 34% compared to the previous year, with hate speech targeting gender, region, and generation accounting for 72% of the total. Recently, violent language online, including digital sexual crimes and malicious comments, has been continuously problematic, leading to the strengthening of related laws such as cyber defamation and the Act on Promotion of Information and Communications Network Utilization and Information Protection. According to Supreme Court statistics, cases prosecuted for cyber defamation in 2024 totaled 12,347, a 37.9% increase from 8,956 cases in 2020. However, at the same time, there is considerable backlash against these regulations, with claims that the law excessively infringes upon freedom of expression. A 2025 public opinion poll by the Korea Press Foundation showed that while 52% of respondents said "hate speech regulation is necessary," 43% responded that "concerns about infringement on freedom of expression are significant." Hate Speech Regulation: Social Responsibility or Excessive Censorship? The core argument for upholding freedom of expression is clear. Democracy thrives through the process of diverse thoughts and opinions clashing and harmonizing. Therefore, if even hate speech were completely excluded, society risks heading towards a state of excessive censorship. Professor Lee Jae-hyeop of Seoul National University School of Law warns that "restrictions on freedom of expression must satisfy the principles of clarity and proportionality, and could potentially be misused as a political tool." Especially in a country with heated political debates like Korea, there is concern that limiting freedom of expression could lead to the formation of public opinion distorted in favor of specific factions. Indeed, cases of account suspensions and post deletions on various online platforms support this. In 2025, a total of 580,000 posts were deleted on major domestic social media platforms, 23% of which were restored after users appealed. However, as The New York Times pointed out, if freedom of expression acts as violence or discrimination against someone, that freedom must be re-evaluated. This movement is also becoming visible in the international co
