A mortgage isn't forced on you against your will lol. Do you understand how consent works? If a woman who has sex hasn't consented to become a parent, nor has a man. That's equality. Why are you so opposed to women having responsibility for their choices? You can have all the power, just have all the responsibility as well. Have a baby, pay for the baby. Or at least give the Father the opportunity to legally opt in. Men are paying for these babies through taxation and labour regardless.
This isn't hard. You either believe in sex equality on this issue or you don't. If women have post-conception reproductive choice, so should men. And if women want 100% of that choice, they should have 100% of that responsibility. ie no child support, no paternal responsibility.
