Already in this country, as a result of the recent controversy, it is written in the constitution of the socialist party that "any member of the party who opposes political action or advocates crime, sabotage, or other methods of violence as a weapon of the working class to aid in its emancipation shall be expelled from membership in the party." Adopted by the national convention of the party in 1911, this clause was ratified at a general referendum of all the membership of the party. It is clear, therefore, that the immense majority of socialists are determined to employ peaceable and legal methods of action.
