A zygote is not a human being. Someone who doesn't want to have a child, who doesn't want to be pregnant is taking responsibility by getting an abortion. "Accept the consequences" is a bullshit specious argument for "don't take responsibility for something you want to be different." If someone falls off of a ladder, do you insist the "accept the consequences", trying to outlaw them from going to the doctor to get the bone set and a cast put on?
"Time to accept the consequences" in the abortion debate is just short hand for "I want to punish you for having sex." What a fucked up raison d'etre you'd impose on children.
