Keygrip,
You are absolutely correct in what you say. Being "professional" and having the ability to put forward reasoned arguement for debate do not seem to form part of the make up here.
Such forums were not designed, I would have hoped, for the display of such personally based vitriol, where possibly libelous statements could be made by an individual hiding behind an anonymous "username" - but is it, bearing in mind some responses, as anonymous as hoped??
