the "Personhood" of a fetus was under debate...since that time, even critics admit that the Magesterium of the RCC has never taught that personhood begins at conception ...and I've posted such documentation more than once, so it isn't me making stuff up (I make it a point to do my homework before posting). If you'd like to debate the "Wiggle Room" issue, just let me know...I'll be glad to join in.
When it comes to states vs the federal government on such issues as abortion, IVF...If you educate yourself...i.e. reading and Critical Thinking...you'll note the myriad of laws in various states prior to the enactment of Roe v Wade...we've been down this road before...and only federal protection (i.e. law) can ensure that ALL women are free to live their lives and make reproductive choices that are theirs and not someone else's.
There are examples being shown right now of women who need abortions due to pregnancies going wrong ('naturally') at 20 weeks and their survival is being compromised because their state won't allow it...and...they don't have the finances to enable them to seek them in another state..........then there are the couples seeking a child through IVF who have already invested thousands of dollars on top of a ton of emotions who are faced with tremendous loss all because their state has chosen to intervene in their laudable and very private reproductive decision.
There are times when federal laws make the most sense...this is one of them.
