That is patently absurd. Consent to sexual intercourse is not consent to pregnancy, especially if contraceptives were used and failed.

At the risk of stretching the metaphor to its breaking point, this is you choosing to go out and get drunk while aware that members of an unethical music lovers' organization are skulking about looking for victims to graft sick violinists onto. Sure, they no longer need to actively drug you because you willingly did that yourself, but that doesn't imply your consent to what happens next.

Consent to sexual intercourse is not consent to pregnancy

It's as much consent to pregnancy as dropping a cinderblock on your foot is consent to a broken toe or eating ten cheeseburgers a day is consent to getting fat.

No, it's really, really not, and this line of reasoning is getting absurd.

People around the world routinely engage in frequent sexual intercourse without becoming pregnant. If you show me even a fraction of that same number of people who have demonstrated an ability to consume ten cheeseburgers a day for a prolonged period without gaining weight, maybe you'd have a point. Otherwise, this is just a blatant false equivalence.

Yes, and people routinely take methamphetamine without having a heart attack and shoot themselves without dying. That doesn't obviate the fact that pregnancy is the direct result of coitus. Claiming you did not consent to the function for which a body part evolved when you used that body part is like saying you didn't consent to sweating when you went for a summer jog. Sure, you may certainly take measures to prevent an undesired outcome but the physical results of your choices can only be tragedy, not injustice.

Consent to eating is consent to taking a dump.
