The terminology "killing babies" is as inflammatory as the discourse that ridicules anyone concerned with abortion and dismisses it as "discarding a bunch of tissue".

Dismissing religious people concerned about abortion as "misogynists" and "supporters of patriarchy" while calling for respect for religious beliefs calling for women to wear hijabs and burqas enflames those emotions and has backfired badly. 

For someone who really believes it is murder, it is not possible to simply accept the "it's her decision" argument.

There is plenty of room for compromise between "government funded abortion on demand" and "no abortion under any circumstances", but taking the stand that nothing less than the the former is acceptable has just led to extreme polarization.
