We really need to get on the same page on this because until we do we look sillier than necessary. It is true that many prayers to Mary and the saints in Heaven are asking for them to pray for us. But we must acknowledge there's more to it than that.
Surely you're familiar with the Memorare and the Salve Regina at least, there's more there than just asking Mary to pray for us.
Nothing in the Bible says we should pray to the Saints or Mary.
