No birth control (aside from sterilization) is 100% effective. If you consider all premarital sex, even "protected" sex, to be irresponsible, then that is a fair statement. But most people do not.
When it comes to elective abortion, I am personally most sympathetic to the case where the couple tried their best to prevent pregnancy and yet it happened anyway. (Of course, there is also the case of rape, where the woman should definitely have the option of abortion.)
