The law does target not Fanatics, but certain fanatical acts. Just like any other law. There is a law against committing murder but not against being a murderer, against committing theft but not against being a thief, etc.
Far more complex than I can understand.
In my simple world, every situation needs to be rationally analysed on its own merits.
That's why keeping fanatic population numbers proportional to your ability to handle their fanatical acts,is vital. Or risk being overwhelmed like Europe.
