Obviously false.
As INDIVIDUALS, we may either respect the right to life or we don't, but there is obviously no such consensus on a national scale.
If there were, laws against abortion would be as commonplace and non-controversial as laws against murder, cannibalism, and dismemberment.
There would be no movement calling for Federalism of the issue, any more than there is now a national movement to make cannibalism a Federal crime.
You have got to be kidding.
The consensus exists in the Preamble to the Constitution, which states that the entire purpose of our Union is to secure the blessings of liberty to ourselves and our posterity. The document then goes on to expressly forbid the deprivation of life, and solidifies that guarantee further in the Tenth and Fourteenth Amendments.
Protecting life is the most basic tenet of our national creed. Without this, government has no legitimacy or purpose.
THere is no consensus and that is the crux of the argument. That is the place where we are and no law will bring about a consensus about this issue.
