Well we'll all try to overlook your over zealous nature my friend.
Up to bat... STRIKE ONE...you're out!
Wrong... we live in a land of laws and those laws are decided by the people who then live under those laws. There are many things that are objected to by various groups, even largely objected to. But in America the majority gets to choose what laws they want and how they want to enforce those laws. They can do this through elections of their representatives and/or through Constitutional Amendments which of course has been done the past.
I understand this is objectionable to the dictatorship known as the Palerider States of America.
However... it is still the case.
And to your earth is flat or round arguement... if the voting majority of Americans wanted it to be legal to... I'll just pick something off the top of my head... say, commit suicide... then suicide could be made 100% legal.
Again I think you are talking a particular religious philosophy (I know I know you'll play the it's not a religious argument game). However many (vastly most) believe that when it comes to personhood a conception has the "possibility" to become a born person but also know there are multiple very natural things that depending on whether they happen or don't happen to transpire dictate if a "person" will be born. That being the case we get involved into the woman's rights.
But regardless I am taking the REALITY of the situation position. We could call conception a cue ball or Frank Sinatra and it would make no difference. Americans see the need for a medical procedure. Woman cannot be forced to carry a child it is not a naturally possible thing to do... and that is why it will continue to stay in effect.
A) That's exactly my point. Abortion like slavery was once ILLEGAL... it was changed to LEGAL some 36 years ago. Your analogy would be correct if you were talking about the hundreds of years slavery was legal before it was overturned.
B) The High Court at anytime can judge on it's own the mindset of the framers. You have a position. There is another position. It's not uncommon for the court to pick a position to help justify it's ruling. Since none of us were in the minds of the framers and abortion was never ever mentioned then one could look at the mindset in the way other rights were granted and draw comparisons to what they didn't come right out and say in other circumstances.
Thank you... exactly my point. AND YET THEY STILL DID NOT GO BEYOND THE WORD BORN! Could they have not just as easily simply said ALL CONCEIVED? Certainly they could have. But they did not. Hence it's logical to assume that the true expression of their mindset was represented.
You can beat this dead horse as long as you want, its not coming back to life. 
Here are the realities of our situation. Roe hasn't been overturned in 36 years even with with your current argument well known. Politicians don't really want Roe overturned because the abortion issue is a good wedge issue. They want to be able to bluster about it... and then say... you know my position but it's up to the courts.
And they act in this manor for excellent reason. Unlike you evidently they are smart enough to realize the real choices are... women are protected as Roe stands or there is a Constitutional Amendment protecting women in that way. There simply is no other path that can stand.
Fortunately with the election of President Obama and during his terms I see at least 3 Justices being replaced at least one a current Conservative (and there could be even more). This issue will remain as it is as even more precedent time passes and the overall court is made even more understanding to the women's rights issue.
Like I've told you pale for close to 3 years now as you keep saying this drastic Anti-Woman change will be happening any day. It's not. Put your efforts to better use helping all the unwanted born children... that would be doing a good thing.
