Show me a dictionary that only supports that definition and does not include holy personages or sacred things? All I can get from your poorly worded posting is that you do not consider the Mother of Jesus worthy of holy status........blasphemy.
I don’t play by y’all’s DAFFYNITIONARY.
With Mary, only the Roman Catholic Church has declared her holy, not God. The dictionary is using blaspheme in a secular sense, like "He commited blasphemy against Islam."
And he opened his mouth in blasphemy against God, to blaspheme his name, and his tabernacle, and them that dwell in heaven. -Revelation 13:6
