By your own arguments,.men are choosing that responsibility by not wearing a condom or taking any responsibility for what happens with their sperm or not electing to be sterilized.

Further, there are no laws that require men to be fathers. There are tens of billions of back child support owed by dead beat dads.

You'll bring up child support, but civil suits are not mandates to fatherhood.

Societal expectations are just that. Expectations. You can say no to those any time you want. You might be unpopular for flouting norms, but you're not required to hold them by law.
