denunciator

Tottle's critics regard him as a "Soviet apologist", or a "denunciator" of the famine.

Dame Rebecca lauded Strossmayer as a "fearless denunciator of" Austro-Hungarian tyranny."

In his newspaper columns, Brossolette had evolved from a resolute pacifist and europeanist, after Aristide Briand's ideals, to a denunciator of both fascism and communism.

The denunciator has a menu from which to choose: outright is forthright, blatant has a ring to it, flat is sharp (though it is often mistakenly replaced by flat-out, which lacks the disapproving connotation) and flagrant lends itself to mispronunciation by stumbling speakers as fragrant.
