Which Bar in Cork - That's where I'm from (Small World huh)
And the Daily Telegraph... really ...... it would be equivalent of reading the Irish Sun in Ireland.
Of course everyone is aware that claiming Irish ancestry is a stretch, but have you any notion of the volume of people who do ?
Does it do anyone any harm, to want to know who they are, where they come from and who came before them.
I don't know what exactly you have against him, nor do I much care to find out, but if I as an Irishman feel quite happy for him to trace back where he's from why can't you ?
Perhaps I may be talking to the wall - perhaps you've already decided you just plain don't like him - may I advise another thread in this case.
(PS - There's in excess of 5,000 Jewish descendants in Cork at any time you weren't the 1st - there has been a Synagogue just off South Mall since World War 2.)
As you are aware it's now nearly 1am here - so Bed time.
