A more thorough explanation:

Legal moralism is a theory that suggests that a government or legal system has the right to prohibit behavior that is considered immoral. This means that laws can be created to prevent actions that are deemed morally wrong, even if they do not directly harm others.

One example of legal moralism is the criminalization of drug use. While drug use may not directly harm others, it is considered immoral by many people and is therefore illegal in many countries.

Another example is laws against prostitution. While some argue that prostitution should be legalized and regulated, others believe that it is immoral and should remain illegal.

These examples illustrate how legal moralism can be used to shape laws and regulations based on moral beliefs, rather than solely on the harm caused by certain actions.
