Since we recognize only one G-d, the myth of the birth of another one is meaningless.
How many types of Christ appear in the Old Testament, do you think?
Such as, for example, Joseph, rejected by his brothers.
Why do these types so appear?
I am very aware of your theology. But I do not share it, and neither does the majority of this country. You can find our “myth” meaningless...fine. But we are not changing the way we have always done things because you have a bad association with it.
Also just for clarification: we do not believe in the “birth of another” God. We believe, as any textbook will tell you, in only one God in three equally divine Persons, the second Person taking on a human nature and entering human history via the womb of Mary.
Just so you have an accurate picture of what you are arguing with.
The birth of Christ is one of the most attested events in history.
You can chose to ignore/deny Him as the Savior of the world and all that it means but you cannot deny His birth.
