Strange, because the KKK opposed the Catholic Church.
Why in the hell would they use the same outfits then?

Rooted in local Protestant communities, it sought to maintain white supremacy, often took a pro-Prohibition stance, and it opposed Catholics and Jews, while also stressing its opposition to the Catholic Church at a time of high emigration from the mostly Catholic nations of Central Europe and Southern Europe.
KKK is not Catholic.
But Protestant shills like you to believe that, of course.
You thought the protestants would not be examined fully? There are just as many skeletons in the closet as all the other religions.
