Mary idolatry is so inveigled in Catholicism of today that no Truth can remove it. Even photographs take at the Fatima event showing a UFO in the sky and matched by eyewitness testimonies which affirm a 'silver disc' int he sky that buzzed the crowd leaving physical effects cannot dislodge the apparitional lies swallowed by Catholic adherents.
IF Rome were to declare their Marian dogmas and/or these apparitions as incorrect the RCC would collapse.
They're so far down the rabbit hole on this and they don't even know it....but it's not as if they've been warned about this.
