Ugh. Really off this morning and for a few minutes this was posted to news. Anyway this is a topic that has come up every so often not only with her kids but back when she was just drawing about herself. I wonder if the swinging arms is intentional given the quote about freedom ending when you make contact with another.
You're doing a good job of encapsulating the Harm Principle
"The harm principle is often explained as 'your right to swing your fist ends where my nose begins.' In other words, people should be free to act as they wish as long as their actions do not cause harm to others."
