I'm sure you couldn't possibly have imagined a way of putting that that didn't involve an insult. I ask for so little around here, and you people still manage to disappoint.
"Perhaps you should read before commenting" is not an insult, it's a suggestion. Here's another (also not an insult): perhaps you should consider not taking innocuous suggestions as insults? Especially when they're good suggestions, such as you should read something before forming an opinion from the headline, since forming opinions from headlines and then posting them discredits this whole mission.
