The person who is attempting to intimidate needs regulation... but feel free to rant on
What you are saying is that the person that is attempting to intimidate needs to be taught a lesson.
So what you are saying is that if someone is staring at me, or if someone is chatting up my girlfriend I should teach that person a physical lesson? This is flawed thinking and will likely cause the lesson teacher to be arrested.
If I am out walking and someone physically attacks me I will defend myself, but not with the intent of teaching a lesson.
Lesson teaching is for the courts.
