Art Thompson, I'm told, is an anti-Catholic, and I believe he is a Mormon. I won't go into who I heard this from, but this man came over to this one person's house, and spewed a lot of anti-catholic rhetoric. This was before he was "CEO" of JBS. This person reported this incident to some others long time in the JBS anonymously.
Years later, he became "CEO." He is not a Catholic, he's quite anti-Catholic, and if he's a Mormon, that would say a lot, because most Mormons are Freemasons. If you've seen any of my posts about Glenn Beck, you might have seen the link I posted regarding SLC and the Satanic imagery contained within their "Temple."
Gary Benoit, the editor of The New American, is a Traditional Catholic. I don't know about McManus. I'll ask some friends.
