John, you might just know the ONLY black man who is a member of the K of C.  They are definitely "white, male, Catholics" and they don't necessarily look to encourage new members who are African-American, Hispanic or East Asian.  Perhaps, the upper levels of the K of C, might look to Hispanics who are in business or government [money and power],
but they are not seeking fellows to join from the poorer levels of society.
 

I remember many years ago, they sought new members from among high school boys [the title for the boys' membership was the Columbian Squires].  But that was before the sexual abuse scandal came out.  I don't know it the K of C has chapters for boys in high school any more.
