The internet  is always a place where things like that happen. you have to remember that you lose the majority of communication cues in typed messages, it's easy to perceive emotional content in another persons posts that doesn't  exist and react to the tone of voice or facial expression you imagine the poster to have rather than the actual content of their words. if you're ever reading a posting and its winding you up, reread it with a broad grin and see its content change.

Any idiot can face a crisis - it's day to day living that wears you out.
