Your definition of "troll" is astoundingly wrong.
People who suffer from Aspergers or Autism (like many Slashdot users) are unable to read those cues in real life, much less on the internet. They are victims of a disease, but your definition lumps them in with people who try to raise the hackles of others on purpose.
If someone does not understand the nuance of your post, it does not mean they are a troll. The inability to read such nuance over the internet is very much akin to Aspergers and Autism. The person on the other end is working at a disadvantage.
It isn't nice to mock the mentally disabled, but you seem to think it's fine. You, sir, are the exact kind of person this story was written about.
