Trying to project 1920s KKK membership into present day Ohio, as Mr. Campin attempts, is nonsense.
Following WW1, Klan membership was at an all-time high in the U. S. and Canada, because of the backlash against immigration policies allowing southern European and Irish Catholics and the extension of rights to the Asian community. Some Protestant groups not associated with the Klan and its ilk attacked the easy access of Irish Catholics and Jews to the U. S. and Canada.
Canada had large Klan memberships in the western cities in the 1920s.
I have a photo taken in a large assembly hall in Calgary of attendance at a KKK rally. In Canada, many business men, as well as tradespeople, were Klan members at the time.
By 1928, the Klan had members in 100 communities in Saskatchewan (historians estimate 25000-50000 members. Their main target in western Canada was the Catholic immigrant, and to some extent Catholics from Quebec.
Last year, a Klan in North Carolina distributed flyers in Hillsboro, Ohio (near Cincinnati in the far south) apparently with no effect). This is the only current report of activity in Dayton that I found.
In the 1920s, the Klan made attacks on the University of Dayton, regarded by them as a center of "Catholic subversion."
I doubt if there are more than a handful of KKK members in the Dayton area.
