No straightforward man can believe, and no fearless man will assert, that a trade union is always right.
 Theodore Roosevelt, Theodore Roosevelt; an Autobiography (1913). copy citation

Context

“Of course, in labor controversies it was not always possible to champion the cause of the workers, because in many cases strikes were called which were utterly unwarranted and were fought by methods which cannot be too harshly condemned. No straightforward man can believe, and no fearless man will assert, that a trade union is always right. That man is an unworthy public servant who by speech or silence, by direct statement or cowardly evasion, invariably throws the weight of his influence on the side of the trade union, whether it is right or wrong.” source
