Kurtz, Vigano, Lori, Cordileone have been speakers or sponsors at NOM , marches in DC ...see quote above.

NOM is an organization that is anti gay and of great interest to the Southern Poverty Law Center.....who has on occasion noted it as a hate group....

There was a close NOM connection to Liberty Council (identified by SPLC as a hate group) and Staver (also a supporter of NOM) and the Kim Davis situation in which Vigano was involved and involved the Pope....

I think the deal is this....starting with Cordileone in an impassioned desire to pass Prop 8 in CA which would affect a whole class of CA citizens who might wish to engage in SSM..NOM was created...with the help  I believe, of the Mormons, and conservative catholic groups....SPLC definitely identified NOM as an anti gay hate group.

This grew with USCCB leadership support...hence the NOM citation noted above.
