It’s because the pro-life movement is no different, fundamentally, from the pro-choice movement; it believes a woman has a right to choose. We can persuade a woman not to make that choice, we can console and help her with healing after she’s made that choice, but we can’t obstruct her from making that choice. That’s her “right” and it’s protected by law. If that weren’t true, and pro-lifers really believed their own rhetoric, they would be blockading every abortion clinic in the country.
You are absurd.
Many of the founders thought slavery was a horrible evil, but they realized that they did not have the power to stop slavery, at our founding, and instead put the new nation on a path that would, eventually, bring the matter to a head.
Recognizing reality, and trying to work within the law, does not make any of us accomplices to the evil involved.
