The Mod Squad 2 post said Calling someone else's post "damned stupid" is not only vulgarity, it is a personal attack. I agree with him. If you said that about my post I would take it as a personal attack which is a violation of ihub rules. On the other hand, if you said "I disagree with your post and here is why I disagree." that would be perfectly acceptable. Attack the message and not the poster.
