My assumption has always been that rights come with responsibilities, hand in hand. Its the main feature of adulthood. You have the right to vote, and you have the responsibility to pay taxes, bills and so on.

Question:

Why, if a female adult has the right to body autonomy, and decides to exercise that right to carry an embryo to full term and deliver a baby, should the male, if he did not want the child, contribute to the child's financial well being?
