I'm trying to understand here... is the fact that all generations shall call her blessed just meaningless in practice? Is it just a theoretical concept that looks pretty in our Bibles but don't actually have any impact in the real world? Is the fact that Jesus said, "Behold, your mother" on the cross just totally meaningless? (Of course people these days tend to think that means nothing for us today, but why in the world is it in the Bible then...?)
I just don't get it. And I may as well add that people who pay no attention to Mary and look at her as just another dead person seem a lot more likely to say heretical things like Jesus Christ's natures were totally separable or that Christ wasn't God when He was hung on the cross or that Christ wasn't actually human and so on ad nauseum... why is this? Because people who try to completely minimize Mary's role in salvation (and often this is a reaction to veneration of Mary by the ancient Churches, namely the Roman Church) end up with a very skewed view of the Incarnation, which leads to all sorts of heresy.
It's all Christological. We don't confess Mary to be the Theotokos just because we like her. We don't venerate her because we think she is a demi-goddess or something crazy like that. Unfortunately that seems to be the popular perception, but it's just plain wrong.
