I'd rather take the sophist decentering of truth over Platonism though. Platonism and it's consequences have been so corrosive, allowing pretending to access to an ordering truth that this allows for systemic oppression (e.g. man is in the image of God therefore superior logics).
We can never escape the sophists because unfortunately their radical critique of truth in language is the case. You can always make evil seem like good and vise versa (never mind good and evil are rhetorically - and materially - determined concepts). Thus there's no shame in "fighting dirty" as it were or, even more aptly, using force instead of rhetoric when necessary.
Edit: tl;dr: who cares who wins debates when you have a ban hammer.
