It would be super easy for them to justify killing fetuses. After all, they have already justified killing:
1. Afghans.
2. Iraqis.
3. Minorities. (By police shootings and otherwise.)
4. Anyone who contracts Covid.
5. Anyone too poor to afford healthcare.
6. The jobless.
7. The homeless.
8. Those around the world who’ve been impacted by various effects of climate change: Wildfires, hurricanes, flooding, crop losses, water shortages, etc.
Conservative logic writes off a whole bunch of humanity from the get-go: but they’re all fair game as long as they are out of the womb.
