it is curious that you have made a good case for inability to prove via scripture either way, yet you have dedicated yourself to supporting the assertion by your religion that Mary not only remained a virgin after giving support to the gestating Jesus, but that she has this long string of venerations (amounting to demi-goddess status) none of which are supported by scriptures even remotely! In the words of the bounty hunter on Serenity, ‘Does that make sense to you?’
The irony of the point you make about the titles given to Mary found no where in Scripture yet so vehemently supported by catholicism is not unnoticed.
