Yet pregnancy is one of them, my point is pregnancy can be prevented in a consensual sex.
Okay, but when consensual sex occurs, there is ALWAYS potential for pregnancy (whether contraception is used or not).
I would argue the goal of sexual intercourse is to reproduce the species, if you use contraception you may 'successfully' prevent that potential child from being born, if you do not use contraception and become pregnant and then instead take a morning after bill, you also prevent the child from being born.
Why is it 'more' acceptable to prevent the biological imperative of sperm and egg to connect at all, then it is to destroy the union of these two gametes ?
