Let me just post the relevant exchanges:
K 'For generations his true character has been obscured by the sympathy English writers felt for him because of his ancestry.'-John Elting. It looks like you've fallen into that trap.
S ..so I take offence at the suggestion that I am influenced by some sort of racial bias
K There was no racial remark made, so please don't go down that route. It's a false trail and the accusation is insulting.
S OK, I should have said national bias rather than racial I suppose, (it was getting late)
How does that add up to me calling you a racist?
As for the blasphemy bit, it was a while back but, as I remember it, someone said that we should consider some other historical figure such as Jesus and I protested about bringing the Lord into it. I never called anyone a blasphemer I'm sure.
I defy anyone to come up with an occasion when I have used a personal attack to refute someone's argument which I take to be the meaning of 'ad hominem'.
