Read this article from the Associated Press.
"It has also raised fears that women might abandon the Roman Catholic Church for other branches of Christianity that allow female priesthood."
The only other “branches of Christianity” that have real priests are the various Eastern and Oriental Orthodox Churches. None of those ordain women to the priesthood either.
I’m assuming the article is referring to various Protestant denominations that "ordain" their ministers, some of which are even called "priests." If that is what is being referred to, then it seems these women care more about that special feeling one gets from a public ceremony and being allowed to wear special clothes than they do about the ontological reality of ordination. Which justs goes to show that it would be wrong to ordain them even if women could be ordained.
