I see nothing wrong with it.
And to call it blasphemy doesn’t fit.
“Saying offensive things about God or religion”
It says nothing offensive about religion, and last time I looked Mary was not a God, though who knows what they’ll come up with next.
It’s wrong from a classic bible faith point of view. That doesn’t mean it’s right for a state to jump in and mediate it either.
If you’re a Catholic you’re going to be super sensitive about Mary and not debase her name and fame. If you’re Protestant you’re not going to want to talk about the departed Mary in hailing terms. So it’s wrong to both views.
