If I may say so...
To me, the big difference between the regular BDF'ers (oh my goodness, that term even SOUNDS like a bad word! LOL!!) who are posting in this thread and the ones to whom this poll is referring to is humility and a willingness to be taught themselves.
We all have strong beliefs and opinions--maybe that's why we all come to a chat site in the first place--so we can share our wealth of knowledge with others!!!
But what I believe sets apart the people posting in this thread from the really hateful ones is that I have also seen these same people apologize to others in the forums and even make jokes at their own expense. And this is just a part of what makes me interested in what they have to say, no matter what the context is.
To me, that's something you never see a "lethal BDF'er" do:
They NEVER say they're sorry.
... And I often wonder if the only crack they'll ever have is the one they sit on, because I most certainly couldn't ever picture them cracking a smile.
