There are types of speech, such as hate speech, defamation, and yelling "fire" in a crowded theater, which have led to calls for limits on internet speech. This is the issue which this essay will develop, the extant to which internet speech ought to be censored.
As an initial matter, it is first important to note how internet speech has impacted knowledge and liberty in positive ways. First, internet speech is perhaps the greatest threat in the world to corrupt individuals and authoritarian governments. It is no longer enough for powerful people and powerful governments to control media outlets in their own countries. This is because people, in China or Thailand for example, can find out what is truly happening in their countries. Thai citizens, to illustrate, can post news stories, international news broadcasts, and personal commentary on the internet in order to inform people back home about what is really happening. In addition, there is a populist aspect of internet speech. Grassroots causes and issues can be communicated to the world at a fraction of the cost of traditional media outlets. In effect, the internet has greatly democratized speech. In addition, the internet has encouraged speech which leads to advances in education.
