Agree that insults are totally unnecessary and counterproductive.
Possibly so, but having read most of the posts, from the poster in question, I'd say that I'm in agreement with Her/Him. Sometimes, when those who speak from experience are contradicted by those who whilst lacking experience, none the less offer theory as fact, then it can become a little frustrating. Failing to contradict nonsense, only serves to support the nonsensical. Frustration can often promote a sharp tongue!
