You have no clue about the Knights of Columbus. They were started by Blssed Father McGivney as a fraternal organization for Catholic men who were barred from other fraternal organizations because of bigotry and discrimination. The KofC also provided life insurance for poor men who worked dangerous jobs (coal mining) so that their widows and children would have a means of support after their deaths. The KofC continues to be a fraternal charity organization and still sells life insurance. The KofC provides sonogram machines to crisis pregnancy centers worldwide.
Why are you posting information that is untrue? Are you just ignorant or do you have an agenda?
The information posted, while by no means the whole picture, was largely true.
The Knights do have a very nominal amount of secrecy (I’m 4th degree) along the lines of what was customary for many U.S. men’s fraternal organizations of the era. While the KKK is a red-flag, the Mason’s would be a better analog.
