Why does anonymity on the internet bring out racism, antisemitism, and all kinds of general hatred, in people?
“Anonymity may reduce the accountability one perceives to have for their actions, and removes the impact these actions might otherwise have on their reputation. This can have dramatic effects, both useful and harmful. In conversational settings, anonymity may allow people to reveal personal history and feelings without fear of later embarrassment. Electronic conversational media can provide physical isolation, in addition to anonymity. This prevents physical retaliation for remarks, and prevents negative or taboo behavior or discussion from tarnishing the reputation of the speaker. This can be beneficial when discussing very private matters, or taboo subjects or expressing views or revealing facts which may put someone in physical, financial, or legal danger (such as illegal activity, or unpopular or outlawed political views). With few perceived negative consequences, anonymous or semi-anonymous forums often provide a soapbox for disruptive conversational behavior.
