It seems to me from reading the first few posts in particular is that though people were offering Sydney some advice, some were also snide and rude at the same time. No wonder this guy's offended, I would be too. We're supposed to be professionals. Which means not only in our business conduct but our "professional" character and attitude.
With that said, if Sydney doesn't want to take advice from some, no big deal. We don't need to resort to "name-calling" because we're professionals and we're better than that.
