To the "false seers", yes. So?
So far, which part of "Catholic offshoots [...] want to deify Mary literally [and they] petitioned the Pope to do just that" do you still claim to be a true statement?
None of it.
Mary is God Dogma
A new movement of Catholics is calling for the proclamation of a dogma elevating Mary to the status of God. This effort is being led by a Marian visionary who claims to have received visions of the Blessed Virgin way back 1994. The visionary's group, MARY-IS-GOD CATHOLIC MOVEMENT (MIGCM), claims Marian Divinity to be the real third secret of Fatima.
