Depends on which part of Louisiana. In southern Louisiana plenty of Catholics. In north Louisiana, not so much. During the construction of St. Joseph church in Shreveport men had to stand guard over the materials because they were threatened by the KKK. This was back in the 20s.
The KKK was active in Iowa back in the 20.
btw; in 1975, the Klan announced an organizing meeting at Unionville in northern Missouri and three men showed up.
Two were deputy sheriffs and one guy was from the FBI in Kansas City.
True, but in 1925 the governor and over half the legislature belonged to the KKK
