Fwiw, Thompson's response to that criticism:
Military draftees?
Granted we don't currently have a military draft in this country, but it's still in use in some places. People forced to serve as their country directs for the common good of that county, for a period longer than nine months, and if there happens to be a war going on during their term of service, they are at risk of dying to save others. We didn't end the draft in this country because we felt it was immoral, but because we came to the conclusion that it was not the most effective way to man the military forces we wanted to have defending us.
As you can see, the argument that requiring an embryo/fetus to be carried to term imposes a level of burden unique to women doesn't hold water with me.
