It is not that easy. I have a former friend who I used to tell over and over she needs to change (get a job, stop being a liberal, take responsibility, lose the anger, etc.). Now we rarely talk.
Further, I tell a lot of people they are fat and need to exercise and lose weight. It does not work.
I'm happily surprised nothing bad has happened to Lebron James yet.
Implicit in my statement "who could tell them to stop" is an understanding that the instruction would be ACCEPTED.
I should have made it more clear.
