I think you have to work real hard to cover your eyes to there being 100% no use, to regarding it as having no potential. Shame on anyone who is able to fool themselves into being so completely convinced.

If you are 99% against, that's at least some ability to judge reality. To have some ability to investigate & think. But you should be able to talk at least like you have some moorings, some connection with both sides of the discussion, imo, or you just aren't being serious.
