well, there's 2 forms of disagreement. I never felt like I was off put by any of dang's comments that I read. AKA a disagreement of tone (in the words of The Big Lebowski: "You're not wrong, Walter. You're an asshole!). He feels professional and won't devolve into flaming like other mods on other sites. He makes his points and lets his sourcing and historical knowledge talk instead of insults or appeals to authority.
Of course there's plenty of times where I disagree philosophically, and that's fine. At the end of the day I'll never fully agree with any one person. I just simply don't want to be called any number of insults you'd hear elsewhere if you dare not tow the line perfectly.
