Changes in Responsibility and Import
[Contraception] destroys unitive intimacy by dividing the couple: the condom places all responsibility on the husband; the pill or diaphragm places all responsibility on the wife. By passing responsibility to one or the other, artificial birth control is blatant sexism, dividing a couple instead of drawing them together in mutual restraint.
As I suggested some years ago, when I traced the psychological progression from contraception to cloning, contraception actually places the responsibility on the birth control method itself. One or the other of the parents is responsible only when he or she fails to use the contraception (in which case there may be practical reasons to mitigate responsibility yet by blaming the nature of the contraception, as with the inconvenience and sensation-dulling qualities of condoms).
