A while ago I had occasion to doubt the usefulness of a certain kind of discussion, which I characterised as piffle. Understandably my doubt was challenged, but the challenge didn't change my view on the matter. I chose not to pursue it, as I didn't expect such pursuit to be fruitful.
I shall not be pursuing this either:
Not just piffle, but risible piffle.
