Opinions on abortion can be moral judgements, but allowing abortion is objectively the better option, since it's going to happen regardless. Not to mention separation of church and state being a thing.

I'm also pro-choice, but this argument isn't very convincing to me. We don't apply the same logic to murder, theft or even drugs, so why apply it to abortion?

One difference is that abortion is verifiably more dangerous when it's illegal, since the mother's health is put at much great risk. Murder is just as dangerous either way.

For drugs there actually is a strong argument for applying the same logic to legalise and regulate them, as it may well reduce harm.

Because we've seen what happens. We have history to rely on. Do you really want to force women to go back to using coat hangers and underground clinics?

Not to mention the medical issues that pop up where it should be explicitly legal, like with young teenage girls or rape victims.

We have seen what happens when any vice is made illegal. People use dirty needles to inject themselves with drugs/HIV, sex trafficking, overprescription of opioids, PC viruses from torrent websites.

Illegality never stops everything, it’s just some subset of embodied ideals.

Morals are learned like everything else. Nothing is entirely a moral judgment (especially taxes?). “indoctrination” is just flat out the wrong word. Being presented facts and views from different angles then reaching the same conclusion most other people reach isn’t “indoctrination”, it’s just education.

Opinions of abortion can be moral judgements. There aren't really many moral arguments about taxation. Or at least I don't know of any.
