Jack is correct to point out abusive language and name calling whenever it occurs Dave.
If this behaviour was taken to its "logical" conclusion, we would have no discussion forum, just a bear pit of abuse, sensible discussion of controversial issues would be impossible.
I can't understand why you would want this sort of childish behaviour to continue, you have always seemed a sensible guy in the past?

The shutting down of civil discussion is always bad, regardless of whether we like what we hear or not.
On this forum ANY subject is up for CIVIL debate.
