Being blessed & cursed with being hypersensitive to, and hypervigilant for, "other people's issues", I don't detect any issues with Nealtw.
And, I don't think he or anyone else here has literally declared himself/herself an expert.
In order to get to the root of this problem, fill in the blanks -
Does he remind you of anyone from your past or present?
What do you believe are his motives in posting?
If you were to charge him with something where the Burden of Proof is on you, what would it be? Make your case.
To whom does this problem belong?
Are there some posts of his that you find particularly offensive? Which one(s)? Why do they offend you?
