Solely your opinion, not supported by facts. I am sure that Elsie can show that the Mormons rejected both Catholics and Protestant alike.
I posted a question in post 293 concerning the WHY this is so important to the Roman Catholic church. Perhaps you are willing to explain.
Why is it important to you (assuming it is) that the Hebrew word almah in Isaiah, Catholic chapter seven, Protestant verse fourteen be not only translated, but believed as virgin instead of young woman ?
