Society has made murder, theft, and rape illegal largely because of a fairly broad-based agreement that those are immoral.

Where there isn’t broad agreement on morality, I would prefer to avoid passing laws to regulate behavior and allow choice. (Roe v Wade/abortion being just one crystal clear case of this tension which I believe is generally best resolved in favor of individual freedom. I am free to follow my own morals where they are stricter than the law; I do not force others to follow them.)
