The magical birth canal
Choice42 makes the point that an arbitrary point in life doesn’t suddenly convey humanity and basic human rights.
The contention from the Left is that there is some magical demarcation point in the life of a child. That before birth it’s just a fetus, clump of cells or a ‘parasite’.
Then in a flash, it suddenly becomes a human being, from mere passage of the birth canal. This video from a couple of months ago illustrates that this is an absurd contention.
