Cowards who use sockpuppets because they aren't willing to pay a reputational cost for their claims.

That form of debate is the proof of stake of public discourse.

They get to claim pure motives for hiding their identities and if they lose the debate, or if their predictions are shown to be false, of if they decide to employ dishonest and underhanded tactics to achieve their goals, then their public identities don't have to suffer.

Fuck them for wanting to have their cake and eat it too.
