Twitter, Facebook and similar services have provided people with easy ways to voice their thoughts at whim. We are now confronted with what everyone should already have known: that people have a lot of irrelevant, illogical, uninteresting, confusing and reprehensible thoughts. I sure do.<p>Every teen has at one occasion thought: I feel like killing [everyone in school, my team, my so-called friends, my brother, the neighbour dog, ...]. Writing such a thought down gives it extra power. A screen doesn't confront you with <i>people</i>, which would make your brain stop and think, so it is easy to misjudge whether you can and should press 'send'.<p>Monitoring that speech and acting on it, directly by the government or indirectly via 'concerned citizens': that way lies police state insanity. It means the system, and many of the people in it, is in denial of the complex, inconsistent nature of humans. They want clear rules, easy judgments, binary divisions between right and wrong. They lose sight of what 'being human' means: a huge variety of things, not all of them pretty, but all of them <i>human</i>.
