You make the logical error of equivocation: from the fact that Gruner was an anti-Semite and a holocaust denier it does not follow that Pope Francis is; from the fact that the Fatima Center is a hate group it does not follow that all persons or groups who are devoted to Mary under the title of Our Lady of Fatima are bigots. Moreover, nothing I posted suggested any of that.
The SPLC and ADL are both well-respected advocacy groups. Your description of them as "hate-groups" says more about you than it does about them.
Catholics ought not allow devotion to Mary to be co-opted by right-wing nuts.
