The Internets Tubes are full of "internet-tough-guys" We have em here too.
I am reminded of this quote
"I asked someone why he did cocaine. He said 'because it intensifies your personality.' I said 'Yeah, but what if you're an *******?'" - Bill Cosby
I feel that the Internets Tubes are the same way. The anonymity allows people's true personality to come out. Many people are stupid *******s.
I am sure that there are Psyc and Social Scientists already studying how this unique form of communication affects people's social judgment.
This is one of the reasons, I would like the anonymity of the Internet to go away. The social experiment has gone on long enough to proof the hypothesis.
