Who were the main targets in the Palmer Raids?

"During the First World War, there was a nationwide campaign in the United States against the real and imagined divided political loyalties of immigrants and ethnic groups, who were feared to have too much loyalty for their nations of origin. Particular targets were Germans, with sympathies for their homeland, and Irish, whose countrymen were in revolt against America's ally, the United Kingdom. In 1915, President Wilson warned against hyphenated Americans who, he charged, had "poured the poison of disloyalty into the very arteries of our national life." "Such creatures of passion, disloyalty, and anarchy", Wilson continued "must be crushed out". The Russian Revolution of 1917 added special force to fear of labor agitators and partisans of ideologies like anarchism and communism. The general strike in Seattle in February 1919 represented a new development in labor unrest that the war had suppressed."
