@anthropy I think a good analogy to draw here is crime. Nobody wants to get robbed or injured or whatever, so obviously people hate crime. Nobody wants crime. But as much as you may shout "crime is bad, it must be banned", it will never go away. Refusing to think about other solutions to protect people only does one thing: make you feel good, because you can declare yourself morally superior by claiming that acceptance of anything beside an absolute ban is accepting crime to a capacity. What many people don't see is that this kind of absolutism is essentially inaction and contributes less to our society than those who they perceive as enemies.
edit: To be clear, the point isn't to say "a little bit of crime is OK". It's to acknowledge that you can't get rid of it entirely and think about solutions with that in mind.
