Why do liberals hate innocent children so much?
You got it twisted. Liberals don't want children bought into a world where a mother is unprepared and they're raised in poverty or worse sent to the system where they may or may not get a good home.
Conservatives don't give a shit about children. They are constantly cutting social programs that help children, against universal healthcare so these children can stay healthy and against public and affordable university that would give these children a chance a decent career and life.
Conservatives obsessions to saving fetuses stems from controlling women's bodies. If men could get pregnant abortion wouldn't be even a discussion. It would be easily and widely available everywhere.
