Each faction of the I. W. W., according to O'Neill, claims to be "the genuine brand of unionism that is ultimately destined to shatter empires, scatter kingdoms and strangle economic slavery to death...."[655] Another editorial in the same journal declares that the Federation is unalterably opposed to their tactics and methods.... Industrial unionism will not come through soup houses, spectacular free-speech fights, sabotage or insults to the flags of nations.... Men will not be organized or educated by means of violence, for violence is but the weapon of ignorance, blind to the cause that subjugates humanity and sightless to the remedy that will break the fetters of wage slavery. There has been less trouble between the coal miners' union and the I. W. W. because the United Mine Workers have always been much less radical than the Western Federation and the I. W. W. has really never succeeded in making inroads of any consequence among the United Mine Workers. Max Hayes, International Vice President of the U. M. W., told the United States Commission on Industrial Relations that the I. W. W. was "rather an unknown quantity among the coal miners. In fact," he said, "we do not let them propagate their doctrines; at least, we try to prevent their ideas from becoming accepted by our people.... There is nothing constructive about their philosophy: it is all destructive."[656] The Mine Workers' Union is perhaps the most constructively business-like, and certainly one of the most successful, unions in the world. Their hard-headed constructive work is most of all evidences in the business agreements which they negotiate with the operators at regular intervals. To the I. W. W., agreements--particularly all _time_ agreements--are in themselves evil. Consequently the friction between the world's smallest and most revolutionary industrial union and its largest and most conservative industrial union was experienced primarily in connection with these agreements. "Wherever the _bona fide_ labor unions have succeeded in effecting a satisfactory agreement with the employers," declares the _Miners' Magazine_, "... there will be found the I. W. W. organizer, attempting to create dissension."[657] The Wobblies justified their attacks upon the Mine Workers [said President John Mitchell at the U. M. W. convention in 1906] by saying that we make trade agreements which so tie the hands of our members as to render us unable to strike at any time during the year when conditions would seem propitious. They lost sight of the fact that if we ... were ... at liberty to strike at our own sweet will, the operators would have precisely the same right and could lock us out whenever trade was dull....[658]
