As a relative newcomer to this forum it has been curious to observe how others deal with the likes of Mr Breadin. He seems to employ all the tactics and language of the bully. Many years ago when I was studying Archaeology at University, we had a very learned tutor who was both revered and feared. While being incredibly knowledgeable on a vast range of subjects there were some that he deemed to be his and his alone and woe betide any pupil who dared to explore them. Anyone who did was instantly shot down in flames and derided in much the same way that your Mr Breadin has done to Simon Costin. He has shown he would rather bully, undermine and shame another individual, than to help and nurture. I'm sure you all know and respect him but from an outsiders perspective his behaviour lacks any kind of respect or grace. I suspect he has behaved in this manner for so long that you are all inured to it. I applaud John Adams for pointing this out but I fear it will have little effect and that well meaning people will be frightened off from ever daring to ask for help or an opinion least they be humiliated in the way that we have all had to witness. Well done to Mr Costin for having the nerve to defend himself but shame on Mr Breadin for having spoiled what might have been an informative and friendly exchange.
