>it just seems a pointless characterization that makes a readers eyes glaze.

On the contrary, they're priming their audience's opinions with masterful efficiency. They're making a bet that their readers will either nod in affirmation, or if they're not in the know about Parler, dismiss it out of hand. Not a defense of Parler on my part, but the cry wolf effect of labeling everything outside the sterile walled garden of limousine liberalism "far-right" is as tiresome as it is unhelpful.
