Why do you think that one rabid dog is different than the other rabid dog?
IMHO, Romney is not a rabid pro-abortion "dog", and I'd rather you would maybe say "rabid raccoon" or something, if you're going to make an analogy to rabies, since I love my dogs, and of course they are vaccinated!!
The abortion situation in the USA has improved tremendously in the years since Roe v. Wade was originally passed. I believe the fact remains that sometimes women will make that choice, especially if they are young and ignorant. They will have it done, however they have to, and not realizing what they are doing to themselves OR to their unborn child.
I can not fault Romney OR his family for realizing that it's better for women to have a real doctor, than it is for them to go to a back-alley coat-hangar clinic, and die themselves as a result, rather than living to regret a bad choice. I would guess the "Planned Parenthood" Organization of the sixties was a much different one than the activists we have today. I can not blame them for wishing that a qualified medical doctor had been available for this sister/sister-in-law, once she made this decision, instead of whoever she went to, and also died as a result.
These back-alley people are always going to be available, no matter what laws, regulations, and restrictions are passed (remember Prohibition?) and women are always going to make this choice...what is needed is to change people's hearts and minds (to quote "W") about abortion, which America has made some good progress on, but we're not there yet.
"Safe, legal and rare" is really just a feel-good buzz-phrase, depending on who's in charge in DC and the Supreme Court, but I would just encourage you to think about what really CAN be done as we go forward, and who would continue to pursue a REAL version of "safe, legal, RARE"?? I don't think abortion will ever be completely illegal again, because too many people will not agree with that point of view, but it's a worthy goal, and you never know!
State laws continue to be passed on time limits, parental notification, etc...and a large majority of the country is against late-term abortions...BUT, unless Roe v. Wade is overturned, the only way America will become completely pro-life will be when enough people agree with this point of view to enact new laws.
Until that happens (if it ever does), I think all we can do is continue to educate our fellow citizens, and elect effective people to office who will continue to work in that direction.
Romney would be a hundred times more in the right direction than Obama.
