i think male facial hair is gross, and i'm right. somebody else might think trans people taking hormones is gross, and i don't give a fuck.
the basis of harm as necessary for a law to be enforceable is central to canadian law, which is why child pornography laws are frequently unenforceable in the court system. conservative mps keep passing laws that try to criminalize child porn because it's offensive, and the courts keep tearing them down because the issues at hand aren't generating any harm to any kids.
anything involving real kids in any way at all can't be allowed, but i can't see any harm in drawing pictures, or writing stories, or singing songs, and the court has upheld that point repeatedly. ai sounds like artistic expression and not like child exploitation, to me.
again - we'll have to see exactly what this guy actually did. but, don't be surprised if the court says something like "the court has no business in the imaginations of the nation".
