Truthiness. You never know how how someone will respond. That is just one reason why the internet is a fantastic place. Nowhere else will you you see the truth of a person so quickly. Anonymity is stronger than alcohol for showing the truth of of a person. Ask the lurkers why they lurk. Of course, there are tricky fuckers out there, in reality as well as digitaly. But its much easier to spot them online. Because anonymity. Even the trickiest can be pegged, eventually, through the filter of anonymity. Everyone fucks up, even geniuses. Its human nature. Even for the inhuman XD Funny shit. So don't be sensitive and defensive. Those are useless emotions.
