I find the idea that men can't have a group which men run to benefit their communities offensive. We are beating the "maleness" out of males. We are beating the courage, energy, and uniqueness out of them! I love, yes love, that men and women have differing qualities and attributes as well as our commonalities. 
The Women's Guilds & other organizations of parishes offer women opportunities similar to and different from KC. Women come together to develop friendship, sorority, and community support.
We should support males developing friendship, fraternity, and community service.
The Knights are a group of men who strive to be God's definition of men. With so much secular emphasis on defining "maleness" in contradiction to God's definition, I support the Knights. 
So, if my choice is support for PP or the Knights... I choose the Knights according to their mission and actions.
