Actually, the history of Lane County is replete with the activities of the Ku Klux Klan, one of whose core beliefs was anti-Catholicism.  
From the Oregon Blue Book" Chapters of the Ku Klux Klan formed in Tillamook, Medford, Eugene, and Portland, as well as many other towns. Robed Klansmen paraded in the streets, ignited crosses on hillsides, nailed American flags to the doors of Catholic schools, and intimidated African-Americans."
 "The Klan, FOPS, and Scottish Rite Masons sponsored a bill, passed in 1922 in the general election, to compel all children to attend public schools. The overtly anti-Catholic measure threatened to close all parochial schools and military academies."
Oregon Encyclopedia
"by 1923 Oregon Klan leaders claimed 35,000 members in more than sixty local chapters and provisional Klans. Hundreds of other Oregonians joined the Women of the Ku Klux Klan, the Junior Order of Klansmen for teenagers, and the Royal Riders of the Red Robe for foreign-born Protestants."
