“Should we never cite a wise word from someone who also said things we disagree with – even if it’s sympathizing with a loathsome political movement?”
The propensity to condemn others, usually writers, for what we might call guilt by inadvertent association is a method of abuse or disparagement often used by those who are incapable of intelligent rebuttal. It is a technique favored by the left and its legion of trolls, who like to point out that an author quoted in a conservative argument has dubious affiliations or, analogously, that the founder of a political organization is responsible for some of the suspicious characters who gravitate around his banner.
In my own case, for example, I have been excoriated for citing passages from Friedrich Nietzsche and Martin Heidegger, who are certainly contestable philosophers, Heidegger in particular. Yet Hannah Arendt, a much beloved political writer among the left and Jewish to boot, was Heidegger’s student and lover and never disavowed him despite his Nazi sympathies. I detest Heidegger and have no truck with his indigestible philosophical tomes, but many of his occasional essays are valuable contributions to modern thought. They should not be readily junked.
More recently, I have been gleefully informed that authors whose insights I have referred to, such as Kerry Bolton and Vilifredo Pareto, among others, were conscripted by fascists. This may be true, but it does not negate the substance of their arguments. Tommy Robinson is another case in point. He is routinely condemned for the outlying circle of mental asteroids – hooligans, Nazi sympathizers – attracted for reasons of their own to his laudable mission protesting the violence and social disruption perpetrated by the U.K.’s growing Muslim community.
