Interesting one.
For example you yourself Fly always make it perfectly clear when posting about Chesterfield that although you make your living here a lot of the time, you don't live here and as such are no affected by decisions made by the council or indeed o occasions the MP.
Now if someone is in the habit of posting on forums and commenting on local councils without making it perfectly clear that they themselves don't actually suffer (or indeed benefit) from any of those decisions then yes I would consider that wrong. Especially if that person does hide behind the anonimity of a forum name such as Town Resident or Chesterfield Dweller.
