Among other things, internet forums like this foster discussion of the issues of the day. A modern day community center, public park, street, or sidewalk for fostering a marketplace of ideas. Condemning such discussion that relates to these important issues as an "internet lynch mob" seems to be to be the equivalent of touting censorship of expression.
Would you prefer the alternative, Mr. CJ001f, that people not express their opinions and thoughts because of fear of being labeled too reactionary?
