because it's a symbolic issue directly connected to the orthodoxy that's defined our society for the past several decades. abortion was enshrined as a defining part of "women's liberation" which in turn is a defining aspect of the "totally not communism we swear guys honest" philosophy that's been trying to shape our society since the 30s. abortion isn't marketed to the average joe as killing babies, it's advertised as a sign of societal advancement, as casting off oppressive old ways of thinking and embracing the (((future))). by denying abortion we're nit just saying "hey killing babies is kinda weird" in their eyes we're literally destroying their future.
