And because comment-section discourses don't happen in real time, commenters can write lengthy monologues, which tend to entrench them in their extreme viewpoint. "When you're having a conversation in person, who actually gets to deliver a monologue except people in the movies? Even if you get angry, people are talking back and forth and so eventually you have to calm down and listen so you can have a conversation," Markman told Life's Little Mysteries.
Chiming in on comment threads may even give one a feeling of accomplishment, albeit a false one. "There is so much going on in our lives that it is hard to find time to get out and physically help a cause, which makes 'armchair activism' an enticing [proposition]," a blogger at Daily Kos opined in a July 23 article.
And finally, Edward Wasserman, Knight Professor in Journalism Ethics at Washington and Lee University, noted another cause of the vitriol: bad examples set by the media. "Unfortunately, mainstream media have made a fortune teaching people the wrong ways to talk to each other, offering up Jerry Springer, Crossfire, Bill O'Reilly. People understandably conclude rage is the political vernacular, that this is how public ideas are talked about," Wasserman wrote in an article on his university's website. "It isn't."
