Dave Gnome,
I say that until he has read the works of all living, eminent, etc. historians he cannot prove it.

I say that I have, or enough of their work to know their opinion on my issues.
In their books and articles the historians refer to each others' work.
No name has cropped up that I have missed. No book has been reviewed in the media of an unknown name.
In three years of arguing, Jim has scoured the net looking for anyone, and I am sure his supporters have too.

If they are worthy of attention their work should be accessible. No such has been missed.
Perhaps Guest Dave will now produce some.
Good luck with that Dave.
