I'm behind you on that one, annalex, but only if we make it verses from Scripture and an empty cross (as big as you want.)
You're right, however. Our culture is sick because much of our culture is godless (or so it thinks.)
Why do you object to the Crucifix?
Christ's suffering is what we go through. Hence the Crucifixion. "We preach Christ crucified".
Mary shows obedience and grace. She is a role model. You do not have to pray to her. Do you go to art museums?
But I would not object to strict Protestant art. It was, for example, a disgrace that they removed the Ten Commandments monument and only a lawyerly meneuver saved the Mount Soledad Cross.
