one of whose purposes or professed purposes is to bring about any governmental, social, industrial or economic change within the United States by the use, without authority of law, of physical force, violence or physical injury to person or property, or by threats of such injury, or which teaches, advocates, advises or defends the use ... of physical force, violence or physical injury to person or property, or threats of such injury, to accomplish such change or for any other purpose, and which, during any war in which the United States is engaged, shall by any such means prosecute or pursue such purpose or professed purpose, or shall so teach, advocate, advise or defend....[707] The penalties proposed in the bill are more severe than in the Australian law. It would punish by imprisonment for not more than ten years or by a fine of not more than $5,000, or by both such fine and imprisonment, anyone who, while the United States is at war, (a) acts as an officer, or speaks as the representative, of such an association, (b) becomes or continues to be a member of, or contributes anything to, such an organization, or (c) publishes or distributes any publication whatever which defends the use of "physical force, violence of physical injury to person or property ... as a means of accomplishing any governmental, social, industrial or economic change." The last section of the bill would impose a fine of not more than $500 and imprisonment for not more than one year, or both, upon any landlord who permits on his premises, while the United States is at war, any meeting of such an association or any assemblage of persons who teach or advocate the use of physical force or violence, etc.[708]
