There are various ideas about morality. But I think even in the most common-sense interpretation of morality, most people agree that there are things that are legal, but immoral, things that are perfectly moral but illegal, and that respecting the law is a meta-rule that is important regardless of morality.
Simple example: Most people agree that cheating on a spouse is wrong and immoral. Not illegal though. Do you think it makes any sense to suggest that the only options are either we change the law to make adultery criminal, or we take vigilante justice on adulterers? Or is it just possible that some things might be immoral (to some people) but should be legal?

Yes, and I think the law was wrong in this case, like it's been wrong many times in history (slavery was once legal too). The correct thing to do was to try and change it, which is what eventually happened.
An incorrect option would've been to jailbreak prisoners because you disagree with the law, despite lots of people being imprisoned for longer than they should've been.
> You are not actually engaging with the argument that the person you are replying to is making. Nobody gives a shit what the law says, they care about what is right and what is wrong. Then we mold the law to match.
I am engaging, because I disagree with this idea. The law and morality are connected, but distinct things, as I've shown above. We have to have legal systems in place to make broad decisions - we can't go based off of people's personal moral ideas. Explain to me how you would like things to work and still be compatible with that idea, given the above examples I've given.
And I think the idea that "nobody gives a shit what the law says" is a statement that is... very, very incorrect.
