They deny this, of course, but I've never seen such a ridiculous cottage industry built around what they call "apologetics". 
If you listen to or watch any of their media outlets (EWTN, Relevant Radio, etc.), you will see a non-stop barrage of pundits--almost none of them ordained, BTW--selling books, websites, etc. opposing pretty much every mainline denomination including the "fringier" ones like Mormonism. They even have an answer for the Orthodox Jews: the far-right clergy in Catholicism just created a whole new religious order for "Mother Miriam", a "star" on EWTN who converted from conservative Judaism.
IIRC, a few years ago, the publishing arm of EWTN had a bestseller book titled When Mormons Call. Yeah, that's the ticket...I don't have any bigger fish to fry than to sit around for years waiting for "Mormons to call" and ring my doorbell--so that I can argue with them about how they're "apostates" unless they RETVRN TO TRADITION AND TRVTH by converting to Latin Mass Catholicism.
