I agree with Borges’ sentiment here. However, my own tirade would simply be a bunch of ad hominem attacks, for the most part.
Any time something is written against me, I not only share the sentiment but feel I could do the job far better myself. Perhaps I should advise would-be enemies to send me their grievances beforehand, with full assurance that they will receive my every aid and support. I have even secretly longed to write, under a pen name, a merciless tirade against myself.
