Politics may well be unavoidable when trying to study human society. Any substantial result is going reflect well or poorly on certain public policies. Economics has its political side but that field still has plenty to offer.

Even presenting correctly extracted value is fraught--if the moral of the story is "by the way, an entire field of academia threw away the truth fifty years ago and has been a joke since then" that moral cannot be presented without being recognized as a partisan position, and thus seen as a political move.

Yes, that's certainly a polarizing position to take.
