I won't google 'witches and the Bible, right now thanks.
For me, it is not an insult, at all- being a withc.
But I am sure, and reading the above would probably confirm- that in obione's mind it surely was an insult. And as such, yes, she did use the word witch first, and with negative and deorgatory intent. So throwing hands up in the air, shouting 'I am innocent' jut doesn't cut the mustard- although I would personally not have complained to HQ- probably no-one did, but HQ saw this for what it was, a clear derogatory insult.
Signing off now- as this forum has just become so vitriolic and so unpleasant in such a underhand way- just do not wish to be part of this at all.
Brexit is enough to cope with on its own.
