Dammit.  I've been trolled once again.
    I have very little tolerance for (what I perceive as) cluelessness
 backed up by arrogance, and something in my personal makeup just can't
 let misinformation stand.  I try very hard to know the difference
 between facts and opinions, and I think I do that much better than many  
As an aside :
In the stonework over a doorway in Southwark (part of 'London' south of
the Thames) is a statement that many here should remember. It's the
doorway of Kilkaldy's Testing Works and reads :
'Facts not Opinions'
