I think your writing is great. Really. This for me is such an interesting concept, because I would have to agree with you. Do you think it's the anonymity that leads to this type of interaction, or the proximity, or lack of a emotional connection, or all of the above? it also allows them to be ruder than they would probably be in person.
I think the answer is D.) All of the above. The psychopathology of internet behavior is indeed an interesting topic. Hmm... I delight in rattling people's intellectual cages, but not in irritating people for the sake of irritating them. I also try hard not to attack individuals. My experience is that basically decent people can hold all sorts of preposterous views. If I make a person have a look at their own assumptions I am doing them an enormous favor -- and if they make me re-examine mine they are doing me an enormous favor too. I see you've only been here a couple of days. I hope it works for you! It's a nice venue, mainly.
