It's almost as if some people just really want it to be legal to destroy human embryos.
In your imaginary land where any people are this hostile, what do you think is done with leftover embryos from fertility treatments, right now?
Do you think they're all frozen forever, just in case someone needs a spare implanted in their uterus?
Do you think that maybe they get grown in secret cloning vats that let them turn into human beings?
Or do you join us in reality land where they're put in a nice clean chamber labeled "biohazard" and hauled off by a medical waste company to be sterilized and destroyed. You're just going to have to learn to live in a reality where huge numbers of embryos are destroyed by the human body, excreted out unnoticed, and untold others are created in a lab so that desperate people can have children, only to be disposed of for a host of reasons, like in-viability or that previous implantations "took". Reality just doesn't treat them the way you imagine they are currently treated.
