I think it's funnier to suggest that they will get pinched on their cute little cheeks. The shooting hostages metaphor makes things sound more serious than they really are. The sky is not falling. Nobody is being a terrorist. The government is just functioning exactly the way it is intended to function. I try to refrain from using metaphors of violence. Such language just feeds the crazies who love to pretend the world is coming to an end.
Sometimes I wish the freedom of speech didn't apply to people suffering from mental illness but it applies to everyone. What can you do?
