Exodus 21:22 KJV - is obviously speaking of a fetus.
It's speaking of the woman bro skillet.
This was never even a passage to condemn abortion. There has never been a time in Jewish or Catholic history where it was standard for the death of a fetus to be paid with eye for eye. For Protestants, I'm not so sure, because there have been a lot of loony Protestants over the past five centuries. But, in those times, and now, it still stands to reason that the death of a fetus cannot constitute murder in an equal sense of murdering another person.
For most of Catholic history, women rather were excommunicated for aborting their fetuses, as it was seen as a general act against nature and a work of perdition. This conviction was largely due to the social gambit of females, living in patriarchy, halting legacy. It's not really a hard thing to realize, except when the bias that it is murder takes over one's perception.
