Try this situation on. You fall in love with a wonderful man. He wants you to meet his mother and father; introduce you to his brothers, sisters, cousins, favorite uncle, etc. I suppose you would refuse him on the grounds that you only "love him" and you don't need all those other people? Will meeting and making room in your live for his family somehow dilute the "personal" nature of your relationship with your beloved? Of course not.
That is what the protestant refusal to get to know the Blessed Mother and the Saints is like to me.
