Igl shows a gross ignorance of Oregon 1920's history by writing "Support for Prohibition, not racism or anti-Catholicism, was probably the No. 1 issue of the 1920s KKK.. Crain wrote of Eugene Klan members in Oct. 26, 1922: “They joined without knowledge of the dangerous nature of the organization .. they joined what they thought to be a patriotic fraternity."
From the Oregon gubernatorial election, 1922 Wikipedia entry "In the early 1920's the Klan had become a powerful political force in Oregon. Ben Olcutt (the current Republican governor from 1919) refused to endorse the Klan. Olcutt's actions nearly cost him the Republican nomination to the Klan backed candidate..The Klan threw their support behind Democrat Walter Pierce who also backed the Klan's Compulsory Education Act..a deliberate attack on Roman Catholic private schools. Both Pierce and the education initiative won wide victories in Nov. 1922"  In 1925 the US Supreme Court struck down the Klan backed Oregon education act.
