Do you have a link to this source?
Apparently like you, I've been wondering why Hatchc has been slow in revealing his source. I found it
here.
Even with this link, I am far from ready to credit the authenticity of the sourcing. Why is no author name present? Why is it virtually impossible to learn anything at all about the people who run the hosting site for this and other articles being deliberately associated with Father Feeney, mostly without justification? Note, for example, that the site's FAQ includes the following disclaimer:
This website has no affiliation with any religion or religious organization and Father Feeney himself, as a traditionalist Catholic and not a “racist” or nationalist, would have vehemently opposed some of its content and some of the sites to which it links.
One needn't be a h0Ɩ0h0αx apologist or a stooge for International Jєωry or one with some degree of sympathy for Monsignor Oesterreicher's subversion of the Faith—I myself am none of these—to desire a bit more forthrightness and forthcomingness from people whose bona fides are, by their own admission, highly questionable.
