Hurt
1. To cause physical damage or pain to; injure.

Hurt has different valid meanings. Accept it and acknowledge that your narrow interpretation of the word and it's intent is wrong and really had nothing to do with the light argument. It was strictly an inflammatory response... OK? Just as your argument about lights and your verbose responses about car headlights that are contrary to DOT regulations. Your arguments are so narrowly focused that you totally disregard the fact that bike lights can be dangerous if not adjusted correctly. Period. The instances don't have to meet some statistical criteria to be considered valid.

This comment alone speaks volumes.
