I've tried to suggest that there are difficulties with separating the person from a personal biographical essay in a way that there aren't in separating the author from an abstract art work.

I don't suppose you feel like engaging with my suggestion with something more than this blunt, unsupported rejection?

If you merely mean that when discussing such a piece we can remain generally calm and give room in the discussion for things other than the author's arrogance, then I agree.
