I take issue with this hypothetical/analogy myself (I’m pro choice) It’s just unnecessary mental gymnastics.

I take issue with the insinuation that a life where sexual activity is limited to stable, long term monogamous relationships isn’t worth living.

Who’s insinuating that? Many single mothers choose to have children

This analogy also assumes that you can divorce pregnancy from sex and thereby from personal choices and responsibility, which you can’t.

But you also shouldn’t conclude that an association is made before hand. Obviously that’s how babies are made and theoretically all risks should be considered before hand, but we’re only human.

A person going for a swim at a pool or the lake/ocean must know they risk drowning. Are they not entitled to help from a lifeguard? Is a person who was bitten by a shark not deserving of care in a hospital?
